Abstract:
A polyurethane-polyol composition comprising the reaction product of:(a) about one NCO equivalent of an n-functional isocyanate compound, wherein n is a number ranging from 2 to abou 5; (b) x moles of at 1 said diol being selected from species wherein the hydroxyl groups are separated by 2 or 3 carbon atoms; and (c) y moles of a compound containing from 1 to 18 carbon atoms and a single functional group capable of reacting with an isocyanate, wherein the sum of x+y is about 0.6 to 1.4 and y=about 0.25x to about 75x, provided t at the NCO/OH equivalent ratio is less than 0.976, wherein said reaction product has an Mn from about 300 to about 3,000.
