Abstract
The invention provides chain extenders made from epoxy-functional (meth)acrylic monomers and styrenic and/or (meth)acrylic monomers. The invention further provides polymeric compositions made from the chain extenders and plastic articles made from the compositions. Finally, the invention provides methods of using the chain extenders to improve the properties of virgin, recycled, and reprocessed condensation polymers.
