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
