NON-ISOTHERMAL CRYSTALLIZATION BEHAVIOR OF BIODEGRADABLE POLY(BUTYLENE SUCCINATE-CO-TEREPHTHALATE) (PBST) COPOLYESTERS
ABSTRACT
Non-isothermal crystallization and subsequent melting of biodegradable poly(bu-tylene succinate-co-terephthalate) copolyesters with different butylene terephtha-late contents were investigated by differential scanning calorimetry measurements. Differential scanning calorimetry crystallization curves revealed that butylene terephthalate contents of poly(butylene succinate-co-terephthalate) copolyesters had an identical effects on the onset, peak and final crystallization temperatures. Subsequent differential scanning calorimetry melting curves implied that both PBST-10 and PBST-70 copolyesters had the narrow distribution of lamellar thickness, while the PBST-50 copolyester showed much wider distribution.
