Abstract:
A process for the preparation of solid crosslinkable water-soluble or water-dispersible compositions, which are capable of free radical polymerization, by functionalizing water-soluble or water-dispersible polymeric binders by causing an unmodified water-soluble or water-dispersible polymeric binder selected from the group consisting of polyvinyl alcohol, polyvinyl alcohol copolymer, polyacrylic acid, polyacrylic acid copolymer, polyvinylamine, polyvinylamine copolymer, or a mixture of two or more thereof, to react with one or more compounds which have at least one group capable of reacting with said unmodified binder and at least one free radical polymerizable group in the presence of one or more polar aprotic swelling agents which are compatible with the binder, selected from the group consisting of organic carbonates, organic phosphates or mixtures thereof.
