摘　　要：用差示扫描量热（DSC），考察了PBT／PET塑料合金在固态缩聚过程中，其热行为随摩尔质量的变化，表明除摩尔质量的影响外，还与共聚物的形成有关。In process of solid state polycondensation of PBT/PET blend, the relation between thermal behavior and its molecular weight is studied by DSC. It is shown that thermal behavior of PBT/PET blend treated with different condition of solid state polycondensation is not only relative to molecular weight, but also relative to formation of copolyester.
