发明名称 Polyamide chain extension process and functionalized polyamides produced thereby
摘要 A process for increasing the relative viscosity (RV) of a reactant polyamide and to products produced by the process. The process includes contacting the reactant polyamide and a chain extender compound, forming the product, and quenching the product when its RV is near its maximum calculated RV value.
