Abstract
Elastomeric polypropylenes modified by grafting and blends thereof with isotactic polypropylenes modified by grafting, and the use thereof as compatibilizers or adhesion promoters for blends and metal composites.
Claims3
A method of imparting increased compatibility to blends of polyolefins and nonolefinic thermoplastics, by adding to such blends, elastomeric polypropylenes (ELPPs) modified with ethylenically unsaturated graft monomers and/or blends thereof with isotactic polypropylenes (IPPs) modified with ethylenically unsaturated graft monomers.
A method of imparting increased adhesion to composites or laminates of polyolefins and metals, by adding to such composites or polyolefins, elastomeric polypropylenes (ELPPs) modified with ethylenically unsaturated graft monomers and/or blends thereof with isotactic polypropylene (IPPs) modified with ethylenically unsaturated graft monomers.
A blend of polyolefins and nonolefinic thermoplastics, containing, as a compatibilizer, elastomeric polypropylenes (ELPPs) modified with ethylenically unsaturated graft monomers and/or blends thereof with isotactic polypropylenes (IPPs) modified with ethylenically unsaturated graft monomers.
