Abstract
This invention relates to thermoplastic moulding compounds with improved properties, in particular with reduced water absorption and rigidity and improved impact strength, from polyamides A and a thermoplastic resin copolymer B containing at least one (meth)acrylic acid ester of a tertiary alcohol in quantities of up to 35% by weight in addition to the other monomers such as styrene or (meth)acrylic esters. The invention also relates to rigid moulding compounds which are tough at low temperatures and are obtained from polyamides and the thermoplastic resin copolymers defined above and in addition contain a rubber polymer C in quantities of up to 35% by weight.
