摘要:

以生物质化工产品衣康酸加氢产物2-甲基丁二酸为原料, 采用熔融缩聚法制备了一种新型聚酯增塑剂聚2-甲基丁二酸1,3-丙二醇酯, 采用红外光谱(FTIR)和核磁共振(1H NMR)对聚酯的结构进行了表征. 通过扫描电镜(SEM)、 动态力学分析(DMA)、 拉伸测试对该聚酯增塑聚氯乙烯(PVC)的增塑效果进行的表征结果表明, 该聚酯与PVC相容性良好, 可大大改善PVC材料的硬度, 增加其断裂伸长率, 降低PVC的玻璃化转变温度、 拉伸强度及拉伸模量. 与小分子增塑剂邻苯二甲酸二辛酯(DOP)相比, 合成的新型聚酯增塑剂具有优异的耐抽出性、 耐挥发性和耐迁移性, 可提高PVC材料的使用寿命.

Abstract:

A novel plasticizer based on the hydrogenation of itaconic acid, poly(1,3-propylene 2-methyl-succinate)(1,3-PPM) was synthesized by 1,3-propanediol and 2-methylsuccinate acid through melt polycondensation. The plasticizing effect in poly(vinyl chloride)(PVC) was characterized. The results showed that 1,3-PPM displayed excellent compatibility with PVC. The glass transition temperature, tensile strength, tensile modulus and hardness of PVC films plasticized by 1,3-PPM decreased and elongation at break increased significantly with the increasing of plasticizer. Furthermore, compared to the traditional plasticizer dioctyl phthalate(DOP), 1,3-PPM had superior durability(volatility resistance, extractability and migration stability).

Key words: Poly(1, 3-propylene 2-methylsuccinate), Poly(vinyl chloride), Plasticizer, Durability
