Patent ID: 6984694

Claim:
A chain-extended polymeric composition comprising: (a) a chain extender comprising a polymerization product of: (i) at least one epoxy-functional (meth)acrylic monomer; and (ii) at least one styrenic and/or (meth)acrylic monomer; (b) at least one condensation polymer; wherein the chain extender has an epoxy equivalent weight of from about 180 to about 2800, a number-average epoxy functionality (Efn) value of less than about 30, a weight-average epoxy functionality (Efw) value of up to about 140, and a number-average molecular weight (M n ) value of less than 6000 and wherein at least a portion of the chain extender has reacted with at least a portion of the at least one condensation polymer to produce a chain-extended condensation polymer wherein the polymeric composition is substantially free of gel particles.
