Abstract

A millable polyurethane gum is prepared by reacting (A) From 10-50 equivalent per cent of a dihydric polyalkylene ether glycol having an equivalent weight of 750-1250. (B) From 10-55 equivalent per cent of water. (C) From 5-60 equivalent per cent of a dihydric alcohol having an equivalent weight between 30 and 90. (D) An amount of tolylene diisocyanate to give an NCO to H ratio (defined) of from 0.900 to 0.990 and (E) At least a catalytic amount of an organotin compound; said equivalent per cent of dihydric polyalkylene ether for a given equivalent per cent of dihydric alcohol being from The term «equivalent per cent» of a particular reactant is defined as the number of equivalents of that reactant divided by the total number of equivalents of water, polyalkylene ether glycol and dihydric alcohol times one hundred. where the term «equivalent» is defined as the quotient of the gram molecular weight of the reactant divided by its functionality. The term «H» includes all the active hydrogen obtained from the hydroxyl groups of the polyalkylene ether glycols, any triol which may be present, the dihydric alcohol and the water. A polyether triol may replace part of the polyether glycol. In Example (1) 2.42 equivalents of polypropylene glycol of MW 2000, 4.20 equivalents of 1,4 butane diol, 3.38 equivalents of water and 9.50 equivalents of a mixture of tolylene diisocyanate isomers were mixed together with stannous octoate. The mixture was poured on to a tray and heated at 90 DEG C. to obtain a gum which could be milled with the addition of diphenyl methane 441 diisocyanate.
