Abstract

Polyoxymethylene/thermoplastic polyether elastomer composites were prepared by using the chain extender based on styrene, methyl methacrylate and glycidyl methacrylate copolymer as the reaction compatibilizer. The composites were fabricated by melt extrusion, and the content of thermoplastic polyether elastomer varied from 0 to 25 phr, while the amount of the chain extender was 0.2, 0.4, and finally 0.6 phr at thermoplastic polyether elastomer content 15 phr. The reactive compatibilization and the properties of the blends were studied. It was found that the viscosity of the blends increased gradually, and the notch impact strength did not change significantly after the addition of chain extender, but the tensile modulus increased significantly.

基于聚甲醛/热塑性聚醚弹性体共混物的多羟基官能化合物的反应相容性

摘要

以苯乙烯，甲基丙烯酸甲酯和甲基丙烯酸缩水甘油酯共聚物为基础的扩链剂，制备了聚甲醛/热塑性聚醚弹性体复合材料。通过熔融挤出制备复合材料，并且在热塑性聚醚弹性体含量为15 phr时，热塑性聚醚弹性体的含量在0至25 phr之间变化，而扩链剂的量为0.2、0.4，最后为0.6 phr。研究了共混物的反应性相容性和性能。发现共混物的粘度逐渐增加，并且在添加扩链剂之后，缺口冲击强度没有显着变化，但是拉伸模量显着增加。
