Abstract
Methods for forming high molecular weight chain-extended condensation polymers are disclosed. The methods include adding a chain extender during the polymerization process of a condensation polymer to provide a chain-extended condensation polymer, wherein the chain extender comprises a polymerization product of at least one epoxy-functional (meth)acrylic monomer, and at least one styrenic and/or (meth)acrylic monomer.
