Urethane forming compositions based on fatty polyols

Claim 1

A composition useful in preparing polyurethanes comprising a mixture of an organic polyisocyanate and at least one fatty polyol of the formula: R.sup.1 --((R.sup.2 --O)--CH--CH--(O--R.sup.3))--R.sup.4 --O--R.sup.5 wherein: R 1 is a monovalent hydrocarbon radical having from 2 to 14 carbon atoms; R 2 and R 3 are individually selected from the group of hydrogen, hydroxyl-substituted alkyl radicals, hydroxyl-substituted alkoxyalkyl radicals and hydroxyl-substituted poly(oxyalkylene) radicals, provided that each radical contains from 2 to 32 carbon atoms and from 1 to 9 hydroxyl substituents and, provided further, that at least one of R 2 and R 3 is other than hydrogen; R 4 is a divalent hydrocarbon radical having from 4 to 14 carbon atoms provided that the sum of the carbon atoms in R 1 and R 4 must be from 10 to 24; and R 5 is selected from the group of hydrogen, hydroxyl-substituted alkyl radicals, hydroxyl-substituted alkoxyalkyl radicals, hydroxyl-substituted poly(oxyalkylene) radicals, provided that each hydroxyl-substituted radical contains from 2 to 32 carbon atoms and from 1 to 9 hydroxyl substituents, and acyl radicals having the structural formula: OC--R.sup.6 --((R.sup.7 --O)--CH--CH--(O--R.sup.8))--R.sup.9 wherein: R 6 is a divalent hydrocarbon radical having from 3 to 13 carbon atoms; R 7 and R 8 are individually selected from the group of hydrogen, hydroxyl-substituted alkyl radicals, hydroxyl-substituted alkoxyalkyl radicals and hydroxyl-substituted poly(oxyalkylene) radicals, provided that each radical contains from 2 to 32 carbon atoms and from 1 to 9 hydroxyl substituents and, provided further, that at least one of R 7 and R 8 is other than hydrogen; and R 9 is a monovalent hydrocarbon radical having from 2 to 14 carbon atoms provided that the sum of the carbon atoms in R 6 and R 9 must be from 9 to 23.
