Abstract

Abstract: Biodegradable poly(butylene-succinate)(PBS) was modified by intoducing 1,4-cyclohexanedimethylene(CHDM) with a stereo structure into the main chain. The results show that a copolymer with a high molecular weight M_n more than 100000 was obtained in 2 h. When 1,4-CHDM increased, the crystallinity decreased but T_g and tanδ increased and the internal friction peak width changed narrow gradually. The 1,4-CHDM content was 30%, the elongation ratio would reach 1232%. All the decomposition temperature of the polymer was above 300 ℃, with a good thermal stability.

Key words: Poly(butylene-succinate), Stereo-structure, 1,4-CHDM, Copolymer, Thermal stability
