摘要: Process for the production of glycidyl (meth)acrylate copolymers with a number-average molar mass (Mn) of 1000 to 6000 g/mol by solvent-free, continuous copolymerisation of glycidyl (meth)acrylate with ethylenically unsaturated monomers, in a reaction vessel with feed and discharge means in the presence of a polyester oligomer, wherein polyester oligomer or a mixture of glycidyl (meth)acrylate copolymer and polyester oligomer is initially introduced in a weight ratio of from 95:5 to 50:50 and the glycidyl (meth)acrylates, further monomers, further polyester oligomer and, optionally, free-radical initiators are added, the addition together with discharge of the copolymers formed being effected in such a way that the residence time required for formation of the desired composition is achieved, and wherein, in the event of the initial introduction of the mixture of glycidyl (meth)acrylate copolymer and polyester oligomer, addition is effected in such a way that the ratio between copolymer and oligomer is maintained.
