Abstract
1289517 Copolyesterpolyols and their polyurethanes INTER-POLYMER RESEARCH CORP 5 Sept 1969 [23 Sept 1968] 44103/69 Headings C3C and C3R Polyurethanes are obtained by reacting a copolyesterpolyol with an organic polyisocyanate wherein the copolyesterpolyol is prepared by equilibrating a mixture of at least two polyols selected from polyesterpolyols and polyetherpolyols at least one of which is a polyesterpolyol, by heating at 150-300‹ C. until the melting point of the equilibrated mixture becomes substantially constant, the copolyesterpolyol having approximately the same melting point as a copolyesterpolyol produced by normal polyesterification techniques and having the same final composition. A process also disclosed for the preparation of copolyesterpolyols comprises equilibrating a mixture of at least one polyesterpolyol and at least one polyetherpolyol, by heating under the above-mentioned conditions. Polyesterpolyols are derived from succinic acid and its anhydride, glutaric acid and its anhydride, adipic acid, pimelic acid, azelaic acid, sebacic acid, phthalic anhydride, isophthalic acid, terephthalic acid, chlorendic acid and its anhydride, tetrahydrophthalic acid and its anhydride with a glycol of the formula HO(CH 2 ) n OH, wherein n is 2-10, diethylene glycol, dipropylene glycol, 1,3-butyleneglycol, neopentylene glycol, lower molecular weight polypropylene glycols, trimethylol propane, 1,2,6-hexanetriol, pentaerythritol, alpha-methylglucoside or sorbitol. Preferred polyetherpolyols include the reaction product of 1,2-alkylene oxides with THF and of glycols, triols or higher polyols with propylene oxide or mixtures of propylene and ethylene oxides. Preferred polyisocyanates are 2,4- or 2,6-toluenediisocyanate; 4,4
