Abstract:

The UV stabilizers 2-OH-4-allyloxybenzophenone and its oxime were prepared. They were copolymerized with styrene to give copolymers containing 2–8% UV stabilizers. The films were exposed to UV light and tested for any change in the carbonyl index, hydroxyl index, tensile strength, elongation at break and evaporation loss. The stabilization efficiency was evaluated by comparing with similar testing on pure polystyrene.

Hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. Tensile behavior, UV transmittance, thermal stability (by thermogravimetric analysis) and dynamic friction of the so exposed PP-based films were determined. Scanning electron micrographs of fractur

Abstract:

Weathering of wood--plastic composites (WPCs) leads to discoloration and cracks, which greatly limits their outdoor application. In this study, light stabilizers (including UV-327, HS-944 and nano-SiO 2 ) were added to the shell of a co-extruded high-density polyethylene-based WPC to improve its anti-ultraviolet (UV) ageing properties and simultaneously to maintain its good mechanical properties. The results showed that UV-327 was the most effective light stabilizer for improving the mechanical and anti-UV ageing properties of the composites among the three stabilizers used.

The preparation of polymeric UV stabilizers by copolymerization of polymerizable UV stabilizers like 2-(2-hydroxy-5-vinylphenyl)-2H-benzotriazole (2H5V) and 2-(2-hydroxy-5-isopropenylphenyl)-2H-benzotriazole (2H5P) with styrene (S), methyl methacrylate (MMA), and butyl acrylate (BA) was studied. Copolymerization parameters for six pairs of monomers, i.e. 2H5V-S, 2H5V-MMA, 2H5V-BA, 2H5P-S, 2H5P-MMA, and 2H5P-BA and UV spectra of the 2H5P copolymers were determined.

Abstract:

A copolyester–limestone composite fabricated with selective laser sintering technology is a potential material for the repair of ancient brick structures damaged by the sun and rain, however the weather resistance of this material must be improved. Herein, UV-236 and UV-328 were employed as UV stabilizers and added into the composite. The results show that the addition of UV-326 and UV-328 effectively inhibited the degradation of CH and ester groups and the formation of hydroxyl, carbonyl, and carboxyl groups. Thus, the stabilizers significantly reduced the color change and decline in mechanic

Abstract One of the major issues in the wood industry is the durability of clear coatings. The addition of organic ultraviolet absorbers (UVAs) improves coating resistance by the absorption and conversion of UV radiation into harmless heat. Organic UVAs are, however, easily degraded by free radicals produced by photodegradation inside the polymer matrix and are prone to migration in the coating. In this study, commercial UVAs and hindered amine light stabilizers (HALS) entrapped into poly(methyl methacrylate) (PMMA) microspheres and CaCO3 templates coated with UV-responsive polymers were added

Abstract:

Nowadays, activities associated with industries, cities, and leisure generate a number of different wastes, including many chemical pollutants that enter the environment and negatively affect the wildlife. Some of them are emerging organic contaminants (EOCs), which include UV filters and stabilizers, antineoplastic agents, and natural and synthetic steroid hormones, among others. It is well demonstrated that the presence of this kind of contaminants may produce adverse effects in aquatic environments and also in marine organisms. Even though the Canary Islands (Spain) are one of the most biod
