Polyamide-polyester composition of improved physical properties
Abstract
Abstract THE SAID POLYAMIDE (C) BEING A LINEAR POLYAMIDE COMPOSED OF AT LEAST ONE DICARBOXYLIC ACID WITH 6-10 CARBON ATOMS AND AT LEAST ONE DIAMINE WITH 6-10 CARBON ATOMS OR FURTHER OF E-CAPROLACTAM AND HAVING A MELTING POINT OF LESS THAN 300*C., AND AT LEAST 20% OF THE ENTIRE CONSTITUENTS CONSISTING OF THE SAID DICARBOXYLIC ACID COMPONENT HAVING A BENZENE NUCLEUS AND/OR THE SAID DIAMINE COMPONENT HAVING A BENZENE NUCLEUS. A POLYAMIDE COMPOSTION ESSENTIALLY COMPRISING: (A) 80 TO 90 PARTS BY WEIGHT OF POLY-E-CAPROLACTAM OR POLYHEXAMETHYLENE ADIPAMIDE, (B) 20 TO 10 PARTS BY WEIGHT OF A LINEAR POLYESTER OF WHICH MORE THAN 80 MOLE PERCENT IS COMPOSED OF ETHYLENE TEREPHTHALATE UNITS (WITH THE PROVISO THAT THE TOTAL AMOUNT OF THE SAID COMPONENTS (A) AND (B) IS 100 PARTS BY WEIGHT), AND (C) 10 TO 60% BY WEIGHT, BASED ON THE SAID LINEAR POLYESTER (B), OF A POLYAMIDE HAVING A BENZENE NUCLEUS OR NUCLEI IN THE MAIN POLYMER CHAIN,
