摘要：

The synthesis of poly(butylene terephthalate), PBT, which contains approximately 3.5 mol% of maleate groups is discussed. The polymer is used in conjunction with unmodified PBT to reduce the particle size of the elastomeric phase in certain polyester/unsaturated rubber blends. This results in an improvement in impact properties compared with control samples which either contain no modified polyester, or an unreactive rubber such as polybutadiene. Model compound experiments indicate that the electron-deficient maleate groups of the modified polyester can react with unsaturated groups in ethylene-propylene-diene terpolymers via an ene mechanism.
