Graft-modified elastomeric polypropylene@ - useful as compatibility promoters and coupling agents in polyolefin/non-polyolefin blends and polyolefin/metal composites

摘要

Elastomeric polypropylene (ELPP) and mixts. thereof with isotactic polypropylene (IPP), which are modified with unsatd. graft monomers, are claimed (I). Also claimed is a process for modifying ELPP and ELPP/IPP mixts. by grafting with ethylenically unsatd. graft monomers (II). Further claimed are blends of polyolefins and non-olefinic thermoplastics, contg. (I) as compatibility promoter.
