新型增容剂在PC/ABS合金中的应用

介绍了三种不同类型的新型增容剂并与传统的增容剂（PE-g-MAH)对比了在PC／ABS合金体系中的改性效果，试验表明，这三种增容剂对PC／ABS合金的增韧比PE－g-MAH效果都要好，其中，增容剂E3比E1，E2具有更好的增韧效果，同时还有增强作用，而且E3在PC／线性饱和聚酯合金体系中也有非常好的增韧效果，这种新型增容剂用量少，成本可接受，为PC合金的性能提高提供了一个较好的选择。

THE APPLICATION OF NEW COMPATILIZER IN PC/ABS ALLOY

Three different kinds of new compatilizers were introduced and compared with the modifying effect of the traditional compatilizer (PK-g-MAH) in the PC/ABS alloy. The results showed the modification effects of the three new compatilizers were better than the traditional compatilizer. Among the three system, the PC/ABS/E3 system had higher strength and rigidity than the PC/ABS/ E1 and PC/ABS/E2 system. When it had hetter toughness. The E3 also had an excellent toughening effect in PC/polyester alloy sys-lem.The use level of the new compalilizer was low, and the cost was acceptable, which provided a good choice on the capability increase of PC alloy.
