Patent ID: 7696285

Claim:
A reactive polymer composition, comprising: an acrylic resin (a′) comprising a functional group (F 3 ) that is at least one of a primary carbamate group, a primary hydroxyl group, a secondary hydroxyl group, or mixtures thereof; and a nonvolatile solvent (b′ nv ), that is not a crystalline solid at 25° C. but is a fluid solid at a free radical polymerization temperature, comprising (i) four or more isomers, and (ii) at least two reactive functional groups F 2 that are selected from primary carbamate, primary hydroxyl, and secondary hydroxyl; wherein no more than 10% of the sum of functional groups (F 2 ) and (F 3 ) are primary hydroxyl groups and at least 60% of the sum of functional groups (F 2 ) and (F 3 ) are primary carbamate groups; wherein the reactive polymer composition is prepared by: providing a mixture (I) comprising: a reactant mixture (a) comprising one or more ethylenically unsaturated monomers; a nonvolatile solvent (b nv ) that is a noncrystalline solid at 25° C., and comprises (i) at least four isomers and (ii) at least one functional group (F 1 ); and at least one reactant (e); reacting the reactant mixture (a) to provide the acrylic resin (a′); reacting the at least one functional group (F 1 ) of nonvolatile solvent (b nv ) with the at least one reactant (e) to provide the nonvolatile solvent (b′ nv ); wherein the at least one functional group (F 1 ) is substantially nonreactive with the reactant mixture (a) under polymerization conditions in which reactant mixture (a) is polymerized, and with the acrylic polymer (a′).
