Claims
- 1. A process for producing a graft copolymer which comprises radically polymerizing in homogeneous solution 0.1 to 2 parts by weight of a monomer mixture of
- (a) 1 mole of a vinyl ester of a C.sub.1 -C.sub.18 -monocarboxylic acid and
- (b) from 0.5 to 3 moles of maleic acid anhydride and/or a semiester of maleic acid and/or fumaric acid with aliphatic C.sub.1 -C.sub.24 -monoalcohols in the presence of one part by weight of a polysaccharide ester of an aliphatic C.sub.1 -C.sub.5 -monocarboxylic acid and in the presence of a catalytic amount of a radical initiator selected from the group consisting of organic peroxides, peroxydicarbonates, readily decomposable azo compounds and short-wave radiation.
- 2. The process of claim 1 wherein the solvent for said homogeneous solution is at least one member selected from the group consisting of tert.-butanol, methylene chloride and glacial acetic acid.
