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.
