Streszczenie:

Multiblock polyethylene-chlorinated polyethylene (PE-b-CPE) copolymers were prepared by partial chlorination of various polyethylenes. The resulting copolymers have partial miscibility with polyolefins, PVC, and chlorinated PVC (CPVC). These copolymers can be used as compatibilizers for blends of PVC with polyolefin elastomers (POE), polyethylene (PE), polypropylene (PP), and butadiene copolymers (ABS/MBS). The efficiency of PE-b-CPE in compatibilizing several olefin-based polymers and copolymers with PVC were studied. A polyolefin elastomer impact-modifier system for rigid PVC compounds was d

The properties of compatibilized blends of polyethylene (PE) and polypropylene (PP), having reduced macromolecular entanglements, were studied. The density of PP macromolecular entanglements was controlled by prior disentangling in solution. The polymer ratio in the blend was 4:1 or 1:4. An ethylene–octene copolymer was used as a compatibilizer. The melt blending process resulted in good dispersion of the minority component, with slightly larger inclusions when more disentangled PP was used. Rheological studies confirmed the achievement of different entanglement densities of PP macromolecules

Abstract Blends of high density polyethylene (HDPE) and acrylonitrile butadiene rubber (NBR) were prepared by a melt blending technique. Dynamic mechanical analysis revealed that elastic modulus has a strong dependence on blend ratio. Loss factor peaks increase with increase in rubber content. Pure components exhibit single Tg whereas two Tgs can be observed in the blends indicating incompatibility between the constituents. Loss modulus data also give similar information. The addition of compatibilizer has only a marginal effect on tan δ peak corresponding to the transitions in NBR. The elasti

The effect of thermoplastic starch (TPS) and banana fiber contents on thermal characteristics of linear low-density polyethylene (LLDPE) matrix were investigated. The measurements from differential scanning calorimetric (DSC) and thermogravimetric analysis (TGA), proved the effectiveness of TPS and banana fiber in improving the blend degradation. On the other hand the LLDPE/TPS/banana fiber composites showed better thermal stability than the LLDPE/TPS blend, which is reflected to the LLDPE chains movement restriction. The incorporation of banana fiber into the LLDPE/TPS blends was found to int

The effect of electron beam (EB) irradiation of high density polyethylene (HDPE) on polyethylene-terephthalate (PET)/HDPE blends has been investigated. The HDPE component was radiation treated before the blend was melt mixed. Although the radiation treatment of HDPE component with 50-200 kGy caused some decrease in the tensile strength and elasticity modulus, the maximum tensile elongation of the blend showed a significant increase (+40%) at optimum dose (100 kGy). The DSC results and the scanning electron microscope images of the fracture surfaces also showed the benefit of a 100 kGy EB-dose
