Thermoplastic molding materials based on a mixture of polybutylene terephthalate and polyethylene terephthalate (a.sub.1), graft polymers having acrylate rubbers as the grafting base (a.sub.2), copolymers of vinylaromatic monomers and acrylonitrile or methacrylonitrile (a.sub.3) and glass fibers (B) have a balanced property spectrum.

Thermoplastic molding composition based on thermoplastic polyesters (a.sub.1), graft polymers incorporating acrylate rubbers as grafting base (a.sub.2), copolymers of aromatic vinyl monomers and acrylonitrile or methacrylonitrile (a.sub.3) and glass fibers (B) have particularly good mechanical properties if the (meth)acrylonitrile content in component (a.sub.3), based on the total weight of (a.sub.3), is less than the (meth)acrylonitrile content of component (a.sub.22).
