Abstract
The disclosed method relates to a method of recycling high relative viscosity nylon. The process involves melting a base polyamide with a dry blended mixture of dicarboxylic acid and a second polyamide. The disclosed method provides a process of controlling the relative viscosity of the combined polyamides and, in various aspects, the second polyamide may be nylon plop or other polyamide having high relative viscosity.
