Abstract
A method of making a polyester comprises heating a mixture of terephthalic acid and another dicarboxylic acid whose glycol ester is stable at 230 DEG C., or of the lower alkyl esters of said acids, and an approximately stoichiometrically equivalent amount of a mixture of a polymethylene glycol of the formula HO-(CH2)n-OH where n is from 2 to 10, and an amount, not in excess of 3 mol. per cent based on the mixture of dibasic acids, of a polyhydric alcohol having at least three hydroxyl groups attached to non-tertiary carbon atoms, at a temperature sufficiently high to melt the mixture, simultaneously removing by distillation volatile products of condensation, and continuing the heating until a stage is reached where filaments formed from the melt can be cold-drawn. Specified dicarboxylic acids are isophthalic acid, sebacic acid and naphthalene dicarboxylic acid. The examples describe the preparation of polyesters in the presence of manganese acetate tetrahydrate from dimethyl terephthalate, dimethyl isophthalate, ethylene glycol and:-(1) and (4) 1:1:1-trimethylol propane; (2) 1:1:1-trimethylol ethane and (3) glycerol, the polyesters being extruded into film form and tensilized.
