摘要：
This article studies the effectiveness of aminolysis in degradation of amorphous material from crystallized polymer. The aminolysis technique of Duong and Bell was used to examine filaments of regular Polyethylene Terephthalate (PET) and of PET-containing sulfur groups (Dacron T9s) which had been subjected to annealing treatments and also to treatment with dimethylformamide (DMF) solutions. While the weight loss curves obtained showed considerable variation with varying pretreatment, results cast considerable doubt on the selectivity of aminolysis and on the feasibility of extrapolating weight loss curves to obtain a measure of crystallinity.
