相容剂的用途

Use of compatibilizer

降低两种聚合物之间的表面张力，促进相的分散，阻止分散相的联并；

Reduce the surface tension between the two polymers, promote the dispersion of phase and prevent the union of dispersed phase.

增加界面层的厚度，增加相间的粘结力，改善热稳定性，增加应力传递效率；

The thickness of the interface layer is increased, the bonding force between phases is increased, the thermal stability is improved, and the stress transfer efficiency is increased.

降低分散相的粒径，形成稳定相结构，为材料提供均一稳定的性能。

Reduce the particle size of dispersed phase, form stable phase structure, and provide uniform and stable performance for materials.

因此，在添加相容剂后，对于原本不相容的体系导致缺口冲击性能上的劣化，可以得到明显的改善。

Therefore, after adding compatibilizer, the deterioration of notched impact performance can be obviously improved for the original incompatible system.
