Abstract
1,146,849. Linear polyesters. MONSANTO CO. 23 June, 1966 [7 July, 1965], No. 28210/66. Heading C3R. In the manufacture of polyesters by reacting a free dicarboxylic acid with a glycol of formula HO(CH 2 ) n OH where n is 2-10, there is used as a catalyst gallium or a gallium-containing compound. Specified gallium compounds are the formate, basic acetate and oxalate; the sulphate, phosphate, trichloride and trifluoride; the phosphide, nitride and antimonide; the oxide and glycoloxide; also triethyl gallate, triphenyl gallate, triethyl gallium, triphenyl gallium and ethyl diphenyl gallium; also sodium gallate. Many aliphatic and aromatic dicarboxylic acids are specified. Examples describe the manufacture of polyethylene terephthalate.
