Thermoplastic moulding compositions of cellulose ester graft copolymers or mixtures thereof with cellulose esters

摘要

Transparent thermoplastic moulding compositions having improved mechanical properties consist of graft copolymers or mixtures thereof with a cellulose ester of aliphatic C1-C5 carboxylic acids, wherein the graft copolymers consist of an ethylene vinyl ester copolymer and a cellulose ester of aliphatic C1-C5-carboxylic acids as the graft substrate, at least part of which being bridged with polymerized grafted units of vinyl esters and/or alkyl esters of acrylic and/or methacrylic acid, and, optionally, C2-C4-olefins.
