Abstract

Poly[(butylene succinate)-co-(butylene terephthalate)] copolymers containing 1 - 12 mol% of butylene terephthalate were synthesized. Their thermal and mechanical properties were investigated. Melting point of poly(butylene succinate) (PBS) homopolymer was 115.2 °C and that of the copolymer containing 12 mol% of butylene terephthalate was 96.7 °C. The crystallinity of the copolymer was decreased from 56.1% (PBS homopolymer) to 41.2% (the copolymer containing 12 mol% of butylene terephthalate). Breaking stress of PBS homopolymer was 37.3 MPa and the value was increased with the addition of butylene terephthalate until it showed the maximum value of 47.0 MPa at the 6mol% butylene terephthalate content: The breaking stresses of the other copolymers were also higher than that of the PBS homopolymer. Breaking strain of the copolymer was increased from 100% for PBS homopolymer to 380% for a copolymer containing 12 mol% of butylene terephthalate.
