摘要：
A new analytical method for the determination of the chemical composition of poly(ethylene terephthalate-co-p-oxybenzoate) is described. The method is based on acid hydrolysis of the polyester sample, subsequent separation of terephthalic and p-hydroxybenzoic acids of different solubility, and UV spectrophotometric determination of both acids.
