Abstract

Abstract:

Poly(butylene methylsuccinate) (PBMS) was prepared using methylsuccinc acid (MSA) and 1,4butanediol (BD) as raw materials. On this basis, the new copolyesterpoly(butylenes terephthalatecobutylene methylsuccinic acid) (PBMT) was synthesized via melt polycondensation from adding dimethyl terephthalate (DMT) to PBMS. The intrinsic viscosity, molecular weight, acid value, hydroxyl value, chemical structure and thermal properties were investigated by means of ubbelohde viscometer, FTIR, 1HNMR, DSC and TGA. The results showed that the intrinsic viscosity and molecular weight reached the maximum while the acid value and hydroxyl value reached the minimum under the conditions that n(DMT+MSA)/n(BD)=1.00∶1.08, n(DMT)/n(MSA)=1∶1. The best copolyester can be synthesized when TBOT and zinc oxide were used as complex catalyst. FTIR and 1HNMR demonstrated that the PBMT was synthesized successfully. DSC and TGA revealed that the thermal property of PBMT had greatly improved compared with PBMS.

摘要： 在1,4丁二醇（BD）和甲基丁二酸（MSA）合成聚甲基丁二酸丁二醇酯（PBMS）的基础上，加入对苯二甲酸二甲酯（DMT），采用熔融缩聚法对其共聚改性，得到一种新型的共聚物聚甲基丁二酸丁二醇酯co对苯二甲酸丁二醇酯（PBMT）。采用GPC、乌式黏度计等测定PBMT的特性黏度、酸值、羟值及相对分子质量，通过FTIR、1HNMR、DSC、TGA研究其化学结构和热性能。结果表明，在n(DMT+MSA)/n(BD)=1.00∶1.08，n(DMT)/n(MSA)=1∶1的条件下，PBMT的特性黏度及相对分子质量最大，酸值和羟值最小；催化剂选择钛酸四丁酯（TBOT）与氧化锌，二者协同效果最佳。通过FTIR与1HNMR测试表明，所需的目标产物PBMT被成功合成。DSC和TGA结果表明，PBMT的热性能比PBMS的热性能有大幅度提高。
