Abstract:
A method for the production of an acrylate polymer in the presence of a liquid diluent comprising the steps of:(1) providing a reaction mixture of at least one A monomer consisting of a monomeric (meth)acrylic acid ester of a non-tertiary alcohol having from 1 to 30 carbon atoms, optionally at least one B monomer different from said A monomer, optionally at least one polymeric graft moiety C having a Tg greater than 20 C, optionally at least one graft macromer D containing repeat hydrophilic units, and at least one liquid diluent which is non-reactive under conditions of free-radical polymerization; (2) forming an acrylate polymer in the presence of said at least one diluent by reaction of component A, and any components B, C and/or D present in said reaction mixture under conditions of free radical polymerization whereby said at least one diluent is non-reactive; and (3) subsequently curing said diluent, and wherein said diluent is selected from the group consisting of: (a) a ring-opening monomer diluent producing a polymer having a Tg<20Â° C., and (b) mixtures of said ring-opening monomer diluent and a multifunctional liquid polymer having a Tg<20Â° C.
