Abstract Biopolyesters, pure and mixed with a compatibilizer, are exposed to UV‐C radiation in the interval 4–32 h. rays act as germicides antibacterial on biomedical materials. The mechanical physical characterization tests have shown how all materials, mixed, undergo photodegradation even if different way. change structural order of polymer, embrittlement, surface wettability water/blood is l...

In this study, polyvinyl chloride (PVC) and polystyrene (PS) polymers, which do not form a compatible blend with each other in certain concentration ranges are widely used on an industrial scale, were used. The range these two polymers determined viscometrically, maleic anhydride-styrene (MAS) copolymer was added as compatibilizing agent range. the polymer pair did 1.5 2.0 g dL-1. range, 5.0 10...

The blending effect of poly maleic anhydride-styrene-methyl methacrylate (MA-St-MMA) terpolymer on non-miscible PVC and Polystyrene was studied depending their thermomechanical properties. Depending the amount synthesized used compatibilizer tensile strength, modulus, properties blends are enhanced. unmodified with small amounts exhibit two-step degradation whereas those containing 6, 8 10 perc...
