POLYESTER MIXTURE WITH IMPROVED FLOWABILITY AND GOOD MECHANICAL PROPERTIES

摘要

THE INVENTION RELATES TO POLYESTER MIXTURES, COMPRISING A) FROM 30 TO 98% BY WEIGHT OF AT LEAST ONE THERMOPLASTIC AROMATIC POLYESTER, B) FROM 0.01 TO 15% BY WEIGHT OF B1) AT LEAST ONE HIGHLY BRANCHED OR HYPERBRANCHED POLYCARBOTE, OR B2) AT LEAST ONE HIGHLY BRANCHED OR HYPERBRANCHED POLYESTER OR A MIXTURE OF THESE C) FROM 1 TO 20% BY WEIGHT OF A POLYESTER BASED ON ALIPHATIC AND AROMATIC DICARBOXYLIC ACIDS AND ON AN ALIPHATIC DIHYDROXY COMPOUND, D) FROM 0 TO 60% BY WEIGHT OF OTHER ADDITIVES, WHERE THE TOTAL OF THE PERCENTAGES BY WEIGHT OF COMPONENTS A) TO D) IS 100%; AND TO THEIR USE, AND ALSO TO FIBERS, FOILS, AND MOLDINGS OBTAINABLE FROM THESE POLYESTER MIXTURES.
