摘 要: | 本文对目前PVC的增韧改性机理以及主要增韧剂种类进行了介绍,同时对目前市场上主要应用的增韧助剂CPE、MBS、ACR的情况进行了介绍。从增韧效果来看,弹性体增韧可以取得良好的增韧效果,但却会使体系的其它力学性能降低,例如冲击强度;因此又出现了非弹性体增韧方法,这种方法不仅可以增韧PVC,并且可以使体系其它力学性能保持不变或是提高。

Abstract: | This article explains the mechanism of the toughening of PVC and the toughening agents, CPE, MBS and ACRo Generally speaking, elastomer toughening can achieve a good toughening effect, but which also destroies other properties, such as impact strength.yet, this problem can be solved by the non-elastomer toughening, which can not only toughening the PVC system, but also remain or promote other properties. |
