Compatibilisation of PP/PA Blends

Blending polymers is widely used for the preparation of new materials. The disadvantage of this application is that the polymer components are usually not compatible and the preparation of blends with suitable (mainly processing and mechanical) properties is not satisfactory. The use of a third compound, called a compatibiliser, is an effective way to ameliorate the end-use properties of the blend. Compatibilisers based on grafted or block copolymers are often used. The present contribution deals with the compatibilisation of polypropylene/polyamide blends with compatibilisers based on grafted or block polyolefines.

W przypadku kiedy polimery mające ulec zmieszaniu nie są kompatybilne stosuje się środki pomocnicze zwane kompatybilizatorami. Często stosuje się kompatybilizatory oparte na polimerach blokowych lub szczepionych. W artykule omówiono mieszanie polipropylenu z poliamidem z zastosowaniem szczepionych lub blokowych poliolefin.
