Abstract
Improved thermoplastic compositions that are resistant to die beard growth are described herein, comprising poly(phenylene ether) resins, polyamide resins and an amount of a beard growth reducing agent selected from the group consisting of non-elastomeric polyolefin resins, partially fluorinated polyolefins, and mixtures of non-elastomeric polyolefin resins and partially fluorinated polyolefins, effective for inhibiting beard growth. The compositions may further comprise at least one impact modifier, flow promotor or filler.
