ABSTRACT:
The present invention provides a polyamide resin composition and a method of preparing the composition. The composition includes a first polyamide resin, a second polyamide resin different from the first, a transition metal, and a lubricant. The first polyamide resin has an extractable fraction of nylon 6 oligomer at least one percent as determined by ISO 6427. The composition is optimized for relative viscosity, viscosity number, moisture content, and an amount of extractables.
