Abstract: The invention relates to thermoplastic moulding compositions consisting of a graft substrate composed of (a) a (meth)acrylic acid C.sub.1 -C.sub.18 -alkyl ester homo- or copolymer, and (b) of a cellulose ester of one or more aliphatic C.sub.1 -C.sub.5 carboxylic acids, and polymerized units of (2) vinyl esters and/or alkyl esters of acrylic and/or methacrylic acid and (3) of C.sub.2 -C.sub.4 -.alpha.-olefins, at least part of the (meth)acrylic acid ester polymer and of the cellulose ester being bridged together through polymerized units of the graft monomers.

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.

Abstract: Transparent thermoplastic moulding compositions having improved mechanical properties consist essentially of a cellulose ester of aliphatic C.sub.1 -C.sub.5 -carboxylic acids and a graft copolymer of an ethylene vinyl ester copolymer having grafted thereon polymerized units of vinyl esters and/or alkyl esters of acrylic and/or methacrylic acid and, optionally, C.sub.2 -C.sub.4 -olefins.
