Abstract:

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.
