Abstract

A polymer composition includes a linear aliphatic polyamide having on average 10 to 14 carbon atoms in the monomer units, an S glass fibre, and a polyolefinic impact modifier. The polymer composition can achieve higher stiffness and impact strength without impairing the ductility. The polymer composition can be used as a moulding material.
