Use of vinylaromatic-diene copolymers in lactam compositions

A lactam composition which comprises the following components: from 3 to 25% by weight of a random vinylaromatic-diene copolymer (A), where the random vinylaromatic-diene copolymer is composed of at least one block (S) which forms a hard phase and which is composed of vinylaromatic monomers, and of...

More Information
Summary:A lactam composition which comprises the following components: from 3 to 25% by weight of a random vinylaromatic-diene copolymer (A), where the random vinylaromatic-diene copolymer is composed of at least one block (S) which forms a hard phase and which is composed of vinylaromatic monomers, and of at least one random block (S/B) which forms a soft phase and which has vinylaromatic monomers and diene monomers, from 75 to 97% by weight of at least one lactam component (B), and also optionally reinforcing materials and/or additives, has improved viscosity in the melt and can be used for producing polyamide mouldings.
