Abstract
A polyamide composition is formed by combining a phosphorous containing catalyst with monomer starting materials under conditions suitable to cause polymerization of the monomer starting material into a low molecular weight polyamide material. The polyamide material, which may include remaining or residual catalyst, is then further polymerized via solid state polycondensation at a temperature suitable to form a high molecular weight polyamide material. The presence of the catalyst results in increased solid state polymerization rate and a final polyamide material composition with increased viscosity and a higher molecular weight.
