THERMOPLASTIC MOULDING COMPOSITIONS ON THE BASIS OF LINEAR SATURATED POLYESTERS CONTAINING ALKALI METAL SALTS OF CYCLIC BORIC ACID ESTERS. THE COMPOSITIONS HAVE USUALLY GOOD CRYSTALLIZATION PROPERTIES.
WHEREIN (A) R REPRESENTS A MEMBER SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND AN ALKYL RADICAL CONTAINING FROM 1 TO 6 CARBON ATOMS, (B) R1, INDIVIDUALLY, REPRESENTS A MEMBER SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND AN ALKYL RADICAL CONTAINING FROM 1 TO 6 CARBON ATOMS, AND (C) EACH N REPRESENTS AN INTEGER FROM 0 TO 3.

FORMATION OF CONTAMINANT DIETHYLENE GLYCOL BY-PRODUCT DURING MANUFACTURE OF POLY(ETHYLENE TEREPHTHALATE) PREPOLYMER BY ESTER EXCHANGE OF DIMETHYL TEREPHTHALATE AND ETHYLENE GLYCOL IN THE PRESENCE OF A CATALYST MIXTURE IS MINIMIZED BY INCLUDING LITHIUM ACETATE DIHYDRATE AS AN ESSENTIAL INGREDIENT IN THE CATALYST MIXTURE WITH ZINC ZCETATE DIHYDRATE AND/OR ANTIMONY TRIOXIDE.
摘要:
MOLDING COMPOSITIONS BASED ON LINEAR SATURATED POLYESTERS AND THE LITHIUM AND/OR SODIUM SALTS OF POLYCARBOXYLIC ACIDS, WHICH MOLDING COMPOSITIONS MAY BE WORKED UP IN THE THERMOPLASTIC STATE AND FROM WHICH MOLDED ARTICLES HAVING A HIGH DIMENSIONAL STABILITY CAN BE MADE. IN THE MANUFACTURE OF MOLDED ARTICLES, ALREADY SMALL AMOUNTS OF THE SAID SALTS BRING ABOUT A HIGH CRYSTALLINITY IN THE HEATED MOLD AFTER A SHORT TIME.
摘要:
THE PRESENT INVENTION PROVIDES A MOLDING COMPOSITION WHICH COMPRISES A LINEAR SATURATED POLYESTER, AN INORGANIC SOLID MATERIAL HAVING A PARTICLE SIZE OF LESS THAN 5 MICRONS AND AN ALKALI METAL PARAFFIN SULFONATE OR AN ALKALI METAL OLEFIN SULFONATE CONTAINING 8 TO 30 CARBON ATOMS, WHICH MOLDINGG COMPOSITION CAN BE WORKED UP IN THE THERMOPLASTIC RANGE AND FROM WHICH MOLDED ARTICLES ARE OBTAINED WHICH CAN VERY EASILY BE REMOVED FROM THE MOLD AND WHICH HAVE A VERY GOOD QUALITY OF THE SURFACE.
