Polymer alloy is a new type of polymer which has two (or more) advantages at the same time by mixing two (or more) polymers with different advantages through chemical and physical methods. Its excellent performance and broad development prospects make it more and more popular. In recent years, the development and industrial application of polymer alloys have made great progress. However, not any two polymers can be well mixed.
The performance of the mixture depends on the compatibility between the two polymers. The mixing of two components with poor compatibility will not only fail to obtain excellent performance, but also lead to the performance degradation of each component and lose practical value. In order to improve the compatibility of components, a simple method is to add a specific polymer alloy compatibilizer. There are many kinds of compatibilizers for maleic anhydride grafting. At present, it is reported that maleic anhydride reacts with polyolefin in screw. Grafting a small amount of maleic anhydride on the polyolefin chain can improve its filling, blending, composite adhesion and other properties.
The main compatibilizers for Maleic Anhydride Grafted Compatibilizer are abs-g-mah, PE-g-MAH, PP-g-MAH and PS (SMA). The compatibilizing mechanism of this kind of compatibilizer is that maleic anhydride group in compatibilizer reacts with hydroxyl end of PC resin to form graft.
