Polymerlegering hvor det som kompatibilisator er anvendt en podet kopolymer av en funksjonalisert polypropylenpolymer og en novolakpolymer

摘要

A polymer alloy produced from (A) a Polymer 1 consisitng of a polypropylene polymer, (B) a Polymer 2, used in an amount of 0.5-95 wt% of the amount of Polymer 1, and containing aromatic monomeric units as repeating unit(s) in the polymer chain and/or having functionality which is complementary to hydroxyl, including functionality allowing for secondary chemical bonds, and (C) a compatibilizer consisting of a reaction product of a functionalized polypropylene polymer having functional groups capable of reacting with hydroxyl groups, and a novolak polymer formed by reacting phenol and/or one or more phenol derivatives with formaldehyde or acetone. The new polymer alloy combines properties which characterize the polypropylene polymer (Polymer 1) with properties characterizing the utilized Polymer 2.
