    摘要： A PROCESS FOR THE PURIFICATION OF BIS(B-HYDROXYETHYL) TEREPHTHALATE, AND PARTICULARLY THAT PREPARED BY THE ESTERIFICATION OF TEREPHTHALIC ACID WITH ETHYLENE GLYCOL, WHICH COMPRISES DISSOLVING ONE PART OF CRUDE BIS(B-HYDROXYETHYL) TEREPHTHALATE IN A HOT SOLVENT, TREATING THE SOLUTION WITH FROM ABOUT 0.005 TO ABOUT 0.5 PART, BASED ON THE BIS(B-HYDROXYETHYL) TEREPHTHALATE, OF A PHOSPHORUS CONTAINING COMPONENT SELECTED FROM PHOSPHORIC ACID, PHOSPHOROUS ACID, AND PHOSPHATE ESTERS HAVING THE GENERAL FORMULA

    O=P(-O-R1)(-O-R2)-O-R3

    WHEREIN EACH OF R1, R2 AND R3 ARE SELECTED FROM HYDROGEN OR STRAIGHT OR BRANCHED CHAIN ALKYL RADICALS HAVING FROM 1 TO 10 CARBON ATOMS, AND WHEREIN THE ESTER CONTAINS AT LEAST AN AVERAGE OF 0.5 ACIDIC HYDROGEN ATOMS FOR EACH PHOSPHORUS ATOM, FILTERING THE HOT SOLUTION AND COOLING THE FILTRATE TO CAUSE PURE BIS(B-HYDROXYETHYL) TEREPHTHALATE TO CRYSTALLIZE THEREFROM.

    摘要： Catalyst-inhibitor system for the polymerization of poly(ethylene terephthalate) having excellent properties for fabrication of fibers and films. The catalyst-inhibitor system comprises a combination of organic or inorganic salts of manganese and cobalt with acetyl triisopropyl titanate and a phosphate ester. This invention also is directed to an improved method of preparing synthetic linear polyesters utilizing the new catalyst-inhibitor system.

    摘要： Copolyesters useful as melt adhesives in the bonding of fabrics, metal, glass, wood, rubber, plastic sheets and other products to produce a bond which will resist the action of heat, steam, dry cleaning solvents and the like, said copolyester being derived from (1) terephthalic acid, (2) adipic acid, (3) ethylene glycol, and (4) 1,4-butanediol or derivatives of these four components. These copolyesters are advantageously improved by the incorporation therein of specific amounts of either sodium stearate or titanium dioxide.
