Abstract: A process tear production of high molecular weight polyamide polymers, such as 6/66 copolymers, using a reactant stream that includes at least one lactam and cyclic oligomers. The stream is reacted with at least one diamine at an elevated temperature ring-open the cyclic oligomers to produce amide pre-polymers that are end-capped with amine groups. The pre-polymers are then reacted with at least one diacid at an elevated temperature to form polyamide 6/66 copolymers. The cyclic oligomers may be formed as by-products during standard polymerization of polyamide polymers from monomers such as caprolactam, hexamethylene diamine and adipic acid.
