Two bio-based polyols (Polyol-r and Polyol-t) were synthesized from commercially available epoxidized soybean oil (ESBO). Polyol-r was obtained from ring opening of ESBO in the presence of fluoboric acid, while Polyol-t from a transesterification of Polyol-r with glycerol through a litharge catalyst. A rigid polyurethane foam was prepared by mixed polyols (Polyol-t and commercial 635 polyether polyol) with 4,4'-methylene-bis (phenyl isocyanate). The hydroxyl value of Polyol-t was higher than that of Polyol-r, which was also backed up by Fourier transform infrared spectrometry. Scanning electro

Currently, most commercial polyols used in the production of polyurethane (PU) foam are derived from petrochemicals. To address concerns relating to environmental pollution, a sustainable resource, namely, castor oil (CO), was used in this study. To improve the production efficiency, sustainability, and compressive strength of PU foam, which is widely used as an impact-absorbing material for protective equipment, PU foam was synthesized with CO-based multifunctional polyols. CO-based polyols with high functionalities were synthesized via a facile thiol-ene click reaction method and their chemi

Abstract In this article, five kinds of soybean oil-based polyols (polyol-E, polyol-P, polyol-I, polyol-B, and polyol-M) were prepared by ring-opening the epoxy groups in epoxidized soybean oil (ESO) with ethyl alcohol, 1-pentanol, isoamyl alcohol, p-tert-butylphenol, and 4-methoxyphenol in the presence of tetrafluoroboric acid as the catalyst. The SOPs were characterized by FTIR, 1H NMR, GPC, viscosity, and hydroxyl numbers. Compared with ESO, the retention time of SOPs is shortened, indicating that the molecular weight of SOPs is increased. The structure of different monomers can significant

Flexible polyurethane (PU) foams were prepared by replacing commercial petroleum-based polyether polyol with palm oil-based polyol up to 50 wt%. Palm oil was converted to polyol by transesterification reaction with glycerol using calcium oxide as a catalyst.

Up to date, no extravagant attempts have been made to use the vegetable oil-based polyols as rejuvenator agents for aged asphalts. In this context, the nature and composition of these biodegradable products need to be identified and physicochemical properties of different nature of compounds need to be measured. Three different vegetable oil-based polyols designed as castor oil polyol, soybean flexible polyol, and soybean rigid polyol were characterized by FT-IR, TLC-FID, 1H-NMR, and 13C-NMR and by the determination of some usual characteristics such as acid value, hydroxyl value, iodine value

The article presents the results of research on the synthesis of a new eco-polyol based on polylactide (PLA) waste and its use for the production of rigid polyurethane-polyisocyanurate (RPU/PIR) foams. The obtained recycling-based polyol was subjected to analytical, physicochemical and spectroscopic tests (FTIR, 1H NMR, 13C NMR) to confirm its suitability for the synthesis of polyurethane materials. Then, it was used to partially replace petrochemical polyol in polyurethane formulation. The obtained RPU/PIR foams were characterized by lower apparent density, brittleness, and water absorption.

It is well known that the traditional synthetic polymers, such as Polyurethane foams, require raw materials that are not fully sustainable and are based on oil-feedstocks. For this reason, renewable resources such as biomass, polysaccharides and proteins are still recognized as one of the most promising approaches for substituting oil-based raw materials (mainly polyols). However, polyurethanes from renewable sources exhibit poor physical and functional performances. For this reason, the best technological solution is the production of polyurethane materials obtained through a partial replacem

Recently, most of the commercial polyols used in the production of rigid polyurethane foams (RPUFs) have been derived from petrochemicals. Therefore, the introduction of modified palm oil derivatives-based polyol as a renewable material into the formulation of RPUFs is the focus of this study. A palm oil derivative—namely, methyl oleate (MO)—was successfully modified through three steps of reactions: epoxidation reaction, ring-opened with glycerol, followed by amidation reaction to produce a bio-based polyol named alkanolamide polyol.

Polyurethanes are a class of materials which can be regarded as filling the gap between rubbery elastomers and rigid plastics and metals. They can exhibit both high elongation and resilience, while retaining high modulus which make them unique for a wide variety of applications in which both stiffness and extensibility is needed. It is now widely accepted that the diverse properties of these copolymers are attributed to the existence of a two phase microstructure. One phase is regarded as a glassy or hard segment, whereas the other phase is considered to be rubbery and to give soft segments. T

In this regard, erodible coatings, based on biodegradable polymer, are used to respond to this problem.

Polyurethanes can be used in many applications by modifying their properties via facile methods. Most of the polyurethanes currently used for industrial applications originated from petrochemical-based chemicals. There is a growing demand in industries to use renewable resources for polyurethanes. Vegetable oil-based polyurethanes have shown properties comparable to that of petroleum-based polyurethanes. In this research, sunflower oil was used as a renewable resource for polyurethanes. Rigid polyurethane foams were prepared using sunflower-based polyols. The polyols were synthesized via epoxi

Polyurethane, as a versatile polymer prepared by the polyaddition of isocyanates and hydroxyl group containing compounds, is widely used in the automotive industry and with an upcoming change of European legislation becomes recycling increasingly important as an alternative to landfilling or incineration. Glycolysis is one of the chemical degradation processes used to transform polyurethane waste using simple glycols as the degradation agents into a raw material. Single phase glycolysis was used to produce recycled polyol from polyurethane semi-rigid foam dedicated for headliner production. Th

Poliovirus is the causative agent of poliomyelitis, a potentially debilitating disease that is a target for global eradication. Vaccination against poliomyelitis is an important tool in the eradication effort, but one of the available vaccines, the oral poliovirus vaccine, contains live, attenuated strains that can revert to virulent forms. Community transmission of so-called vaccine-derived polioviruses (VDPVs) can contribute to outbreaks, including in areas with no recently reported poliomyelitis cases. Wastewater-based surveillance (WBS) is a widely applied method to monitor communities for

Streszczenie:

The objective of this study is to develop a new conductive thermoplastic material with superior electrical properties. Currently, conductive polymers are typically filled with carbon or metallic particles [1]. However, these filled thermoplastics exhibit drawbacks such as high rigidity, toxicity, and high viscosity [2]. An alternative approach investigated in this work is to substitute these fillers with intrinsically conductive polymers like Poly(3,4-ethylenedioxythiophene) (PEDOT). PEDOT can achieve exceptional electrical conductivities (over 1000 S.cm-1) when combined with polymeric dopants
