柠檬酸对合成聚丁二酸丁二醇酯性能的影响
Effect of Critical Acid on the Property of Synthesized Poly(butylene succinate)
摘要
Abstract
Branched or slightly crosslinked poly(butylene succinate) was synthesized by direct melt polycondensation of succinic acid, 1,4-butanediol and critical acid. The structure of c-PBS was characterized by 1HNMR. The properties of PBS were characterized using Ubbelohde viscometer, DSC and test instrument of mechanical property. The results show that: the gelation, intrinsic viscosity, tensile strength and tensile modulus of PBS increase with the increasing of critic acid content, but the elongation at break decreases. The introduction of critical acid is in favor of the molecular chain crystallization of PBS, and also can make the crystallization temperature increase.关键词
