PROCESS FOR PREPARING POLYMER ADDITIVES AND POLYOLEFIN COMPOSITIONS WITH IMPROVED PAINT ADHESION

摘要

A process for preparing polyolefin additives containing hydroxy groups by reactive coextrusion of a polymer A containing dicarboxylic anhydride groups with at least one organic compound B having at least two hydroxy groups and a process for preparing a modified polyolefin composition containing hydroxy groups comprising the mixing of a polyolefin C with such polyolefin additives.
