A compatibilizer and modifier for polymeric compositions comprising polyolefins

摘要

A polymeric composition comprising a first, second and third component. Said first component being a first polymeric material comprising C2 to C20 linear or branched stereoregular polyolefins (isotactic polypropylene). The second component is a polymeric material comprising linear isotactic polymers having a structure of one or several C2 to C20 olefins, the isotacticity of the polymers in said second polymeric material due to a statistic distribution of stereoscopic error in the polymer chain. The third polymeric material comprises C2 to C20 linear or branched stereoregular polyolefins (atactic or syndiotactic polypropylene), the tacticity of said third polymeric material being different from the tacticity of the first polymeric material. The second polymeric material is a compatibilizer for the first and third polymeric material.
