Abstract

Abstract: Poly(propylene carbonate)(PPC)(copolymer of 1,2-epoxypropane and carbon dioxde) was blended with the esters of carboxylated poly(2,6-dimethyl-1,4-phenylene oxide),(E(x)C^yPPO).The effects of the degree of substitution and chain length of the substituents in E(x)-C^yPPO on the miscibility of PPC/E(x)-C^yPPO blends were discussed.The miscibility of the blends is increased with the increase of the content and the chain length of the substitute groups in E(x)-C^yPPO;however,the blend is immiscible when the content of substitute groups in E(x)-C^yPPO was low and the chain length was short. FTIR data indicated that there is a specific interaction between PPC and E(12)-C³²PPO.

Key words: poly(propylene carbonate), carboxyl ated poly (dimethyl-phenylene oxide), miscibility
