摘要

采用适当的聚丁二甲酸乙酯（PEST）配方和添加剂，制备了熔融温度高（Tm; 150℃）、抗拉强度大（33.7 MPa）、伸长率高（740%）、特性粘度低（I.V.; 0.89 dL/g）、硬度适中（66 Shore D）、变色程度低（b∗值= 2.1）的改性PEST复合材料，并最终采用T-Die挤出法制备了食品包装膜样品，通过了生物降解性试验。此外，还生产了一种基于PEST的热熔胶，其中含有改性PEST复合材料、扩链剂、润滑剂和增粘剂。实验结果表明，改性PEST复合材料是一种很有前途的用于食品包装薄膜和热熔胶的可生物降解复合材料。

Manufacture of modified biodegradable poly(ethylene succinate terephthalate)(PEST) composites and their feasible evaluation for food package films and hot melts

With appropriate recipe of poly(ethylene succinate terephthalates)(PESTs) and additives, a modified PEST composite possessing high melting temperature (T_m; 150 °C), great tensile strength (33.7 MPa), good elongation (740 %), low intrinsic viscosity (I.V.; 0.89 dL/g), moderate hardness (66 Shore D), and low discoloration (b∗ value = 2.1) has been prepared and its prototype of food package film has eventually been fabricated with T-Die extrusion, passing the biodegradability test. Furthermore, a PEST-based hot melt with the modified PEST composite, chain extender, lubricant, and tackifier has also been manufactured. Experimental results demonstrate modified PEST composites are promising biodegradable composites for food package films and hot melts.
