Abstract
Nylon 6 molding and extrusion grade resins are stabilized against UV degradation by the addition of small amounts of carbon black. The elongation and impact strength of the nylon are preserved, if not improved, by melt blending from 5% to 50% by weight of an elastomeric polyester with the nylon and carbon black.
Claims2
A UV stabilized nylon 6, a polymer of caprolactam, containing about 0.5% to 5.0% carbon black, the improvement comprising the addition of from 5% to 50% by weight of a polyester elastomer.
A method for improving the impact properties of a nylon, a polymer of caprolactam, 6 molding resin filled with carbon black, which comprises melt blending 5% to 50% by weight of a polyester elastomer with the nylon and carbon black.
