Abstract

A copolyamide composition comprising a statistical copolyamide containing 70-99 wt % of diamine and dicarboxylic acid repeat units and 1-30 wt % of lactam or AA-BB repeat units, whereby incorporation of the comonomer lactam or AA-BB unit reduces the crystallization rate (longer crystallization times) while maintaining (1) high melting point, (2) low potential plate out, (3) low oxygen permeation, (4) high tensile strength and (5) puncture/tear resistance.
