Abstract

Thermoplastic moulding compounds based on fully aromatic polyester carbonates polyalkylene terephthalates and grafted diene rubber have a well balanced combination of notched impact strength at room temperature and low temperatures and high weld line strength and may be used for the production of moulded articles, in particular by injection moulding.
