摘要：

The liquid-induced crystallization of bisphenol-A polycarbonate films in the presence of CCl4 and acetone as swelling agents has been investigated by means of differential microcalorimetry and differential scanning calorimetry (d.s.c.). Results of microcalorimetric measurements were used to obtain thermokinetic curves and to determine heat effects in the liquid-induced crystallization process. Results of calorimetric measurements were subjected to Avrami analysis. The d.s.c. experiments revealed a maximum crystallinity of about 17% in the case of samples swollen in CCl4 and 20% for those swollen in acetone. © 1979.
