高分子共混物中组分的不相容性会导致共混物的性能下降.因此,对高分子共混物的增容是很必要的.环氧树脂具有很高的反应活性,价格低廉,且在同时提高聚合物的强度和韧性方面大有发展,文中对环氧树脂作为增容剂的增容机理及其对共混物性能的影响、应用体系以及影响增容的各种因素作了分析和评述,对这一领域的发展趋势进行了展望.
The immiscibility of polymer blends results in products with inferior properties than the average of the base polymers. Research on compatibilizer is particularly valuable. Epoxy has been demonstrated as a low cost and high chemical reactivity compatibilizer, it has a bright future in increase the strength and toughness of polymer blends at the same time. In this paper, the mechanism of compatibilization using epoxy in blends and the effect of epoxy on the properties of blends were reviewed, and the chemical reactions they undergo during melt blending were presented. An appropriate quantitative epoxy can improve the rheological, thermal and mechanical properties of blends. The future trend of epoxy compatibilizer was also suggested.
