Block copolyamides.

摘要

Block copolymers obtainable by mixing A) a melt of from 15 to 85 % by weight of an amorphous polyamide (nylon) prepolymer having a viscosity number of from 40 to 100 ml/g with B) a melt of from 15 to 85 % by weight of a partially crystalline polyamide prepolymer having a viscosity number of from 40 to 100 ml/g, and C) from 0 to 70 % by weight of conventional additives and processing auxiliaries in effective amounts, followed by post-condensation in the solid phase, where the percentages by weight of components A) to C) add up to 100 %.
