工程塑料PBT增韧改性的研究进展

摘要

The structure characteristics and properties of poly ( butylene terephthalate) ( PBT) were introduced, and the main toughening modification methods of PBT were reviewed. Among them, core~shell structured polymers with reactive functional groups were most widely used. The toughness and other mechanical properties were enhanced simultaneously.%阐述了聚对苯二甲酸丁二醇酯(PBT)的结构特点、特性及PBT增韧改性的主要方法,尤其是带有反应性官能团的核-壳结构改性剂是增韧改性PBT的一种趋势,在提高材料韧性的同时,可提高材料的其他力学性能.
