NON-ISOTHERMAL CRYSTALLIZATION BEHAVIOR OF BIODEGRADABLE POLY(BUTYLENE SUCCINATE-CO- -TEREPHTHALATE) (PBST) COPOLYESTERS

Abstract

Non-isothermal crystallization and subsequent melting of biodegradable poly(butylene uccinate-co-terephthalate) copolyesters with different butylene terephthalate ontents were investigated by differential scanning calorimetry measurements. ifferential scanning calorimetry crystallization curves revealed that butylene erephthalate contents of poly(butylene succinate-co-terephthalate) copolyesters ad an identical effects on the onset, peak and final crystallization temperatures. ubsequent differential scanning calorimetry melting curves implied hat both PBST-10 and PBST-70 copolyesters had the narrow distribution of lamellar hickness, while the PBST-50 copolyester showed much wider distribution.
