Thermoplastic moulding compositions of co-graft polymers which are obtained by the polymerization of vinyl monomers, in particular by the polymerization of unsaturated esters, in the presence of mixtures consisting of the following:

Thermoplastic moulding compositions of co-graft polymers

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.

Thermoplastic moulding compositions of cograft polymers of cellulose

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.

Thermoplastic moulding compositions of cellulose ester graft copolymers

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.
