EFFECT OF SUBSTITUENTS ON THE MISCIBILITY OF POLY (PROPYLENE CARBONATES) AND ESTERS OF CARBOXYLATED POLY(2,6-DIMETHYL-1,4-PHENYLENE OXIDE)
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,PPO).The effects of the degree of substitution and chain length of the substituents in E(x)-CyPPO on the miscibility of PPC/E(x)-CyPPO 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)-CyPPO;however,the blend is immiscible when the content of substitute groups in E(x)-CyPPO was low and the chain length was short. FTIR data indicated that there is a specific interaction between PPC and E(12)-C32PPO.
