HIGH MOLECULAR WEIGHT BRANCHED POL(ALKYLENE TEREPHTHALATE)

摘要

A process for the preparation of branched poly(alkylene terephthalates) and mixtures of poly(alkylene terephthalates) is disclosed. The process comprises intimately blending the linear polyesters with a branching component, transforming the blend to a particulate state, and solid state polymerizing until a copolyester having the desired molecular weight is achieved.
