Patent ID: 8268923

Claim:
A process for producing solutions of vinyl polymers in reactive monomers, comprising a) free-radical-initiated polymerization by bulk-, suspension- or solution-polymerization processes of one or more ethylenically unsaturated monomers selected from the group consisting of vinyl esters, acrylic esters, and methacrylic esters, and optionally also one or more other ethylenically unsaturated monomers, provided that one or more inert solvents are present if the free-radical-initiated polymerization is suspension- or solution-polymerization, and then b) optionally removing volatile constituents by distillation, c) optionally adding one or more inert solvents, provided that if the free-radical-initiated polymerization is bulk polymerization, the one or more inert solvents are added, d) mixing with one or more reactive monomers, and e) removing the inert solvents of steps a) and/or c) by distillation, wherein in all of the steps of the process prior to and during the mixing with the reactive monomers, the vinyl polymers are present in a flowable form.
