Abstract
Transparent thermoplastic moulding compositions having improved mechanical properties consist of graft copolymers or mixtures thereof with a cellulose ester of aliphatic C.sub.1 -C.sub.5 carboxylic acids, wherein the graft copolymers consist of an ethylene vinyl ester copolymer and a cellulose ester of aliphatic C.sub.1 -C.sub.5 -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, C.sub.2 -C.sub.4 -olefins.
