PTA和CHDM改性聚丁二酸丁二醇酯的性能比较研究
Performance comparison of poly(butylene succinate)modified by PTA and CHDM
摘要
Abstract
PBS-co-PTA and PBS-co-CHDM random copolymers are obtained, taking tereph-thalic acid (PTA) containing benzene ring and 1, 4-Cyclohexanedimethanol (1,4-CHDM) with six- membered ring into PBS main chain. The product copolymers are identified to be expected by ]HNMR, and molecular weight, thermal properties, mechanical performance and degradations of them are also compared. The results show that PTA and 1,4-CHDM modified copolymers present different crystallinities; with increasing contents of PTA, crys-tallinity and crystal size of PBS-co-PTA increase, while Tg gradually reduces; and along with the increase of 1,4-CHDM, crystallinity and crystal size of PBS-co-CHDM decrease, but Te gradually increases. When the content of 1,4-CHDM is to 30%, the elongation at break of PBS-co-CHDM is three times that of PBS, which proves PBS-co-CHDM has better flexibility than PBS-co-PTA.关键词
