  • Blends of thermotropic polymers with polyesters and polycarbonate
    Patent number: 5011884
    Abstract: A polymeric molding composition contains(a) 20-70% by weight of a thermotropic, liquid-crystalline polymer(b) 10-50% by weight of a polycarbonate(c) 10-50% by weight of a polyester, the weight percentages (a), (b) and (c) adding up to 100, and(d) up to 60% by weight, based on the total amount of proportions (a), (b) and (c), of further polymers, fillers, reinforcing agents, processing aids or other additives, and is used for producing moldings, fibers, films or coatings.
