A method comprising: adding a chain extender during the polymerization process of a condensation polymer, providing an extended chain condensation polymer, wherein the chain extender comprises a polymerization product of at least one monomer (met) functional acrylic and at least one styrene monomer, substituted styrene monomer, (meth) acrylic monomer or a mixture of any two or more thereof; and process the extended chain condensation polymer by solid state polymerization; wherein: the functional (meth) acrylic monomer has an epoxide, anhydride, carboxylic or hydroxyl function and the condensation polymer is a polyester, polyamide, polycarbonate or biopolyester. |
