摘要: 聚合物共混物相容性影响其性能.加入非反应性的共聚物、反应性聚合物及低分子量化合物等可使共混物的增容,或通过熔融反应就地形成接枝共聚物.聚丙撑碳酸酯(PPC),是由二氧化碳和环氧丙烷聚合而成的新型含端羟基脂肪族聚碳酸酯,是一种粘性体,可作为 PVC 的长效增塑剂.

Abstract: Poly(vinyl chloride)/poly(propylene carbonate)blends are prepared by methods of solution and melting,and are proved immiscible by DSC,but their immiscibility degrees are affected by molccular weight and blending ratio.PVC content in PPC-rich phase in solution blends is calculated according to glass transition temperature(Tg).As coupling agent, NBR-PPC elastomer has a great compatibility effect on PVC/PPC blends.The amount and molecular weight of PPC influence the mechanical properties of PVC/PPC blends.

Key words: poly(vinyl chloride), poly(propylene carbonate), coupling agent, compatibility, mechanical property
