Abstract:
1. A poly(ureaurethane) consisting of a reaction product of components, wherein the components used to prepare the reaction product are free of polyester polyol, polycarbonate polyol, polyether polyol and amine curing agent, the components consisting of: (a) at least one isocyanate functional ureaurethane prepolymer consisting of the reaction product of: (b) at least one polyisocyanate and at least one aliphatic polyol, wherein the aliphatic polyol is selected from the group consisting of ethylene glycol, diethylene glycol, triethylene glycol, 1,2-ethanediol, propanediol, butanediol, pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, dodecane diol, sorbitol, mannitol, cyclopentanediol, 1,4-cyclohexanediol, cyclohexanedimethanol, 1,4-benzenedimethanol, xylene glycol, hydroxybenzyl alcohol, dihydroxytoluene, 1,4-bis(hydroxyethyl)piperazine, N,N′,bis(2-hydroxyethyl)oxamide, glycerol, glycerin, tetramethylolmethane, trimethylolethane, trimethylolpropane, erythritol, pentaerythritol, dipentaerythritol, tripentaerythritol, and mixtures thereof, and wherein the ratio of number of isocyanate groups of the at least one polyisocyanate (b) to the number of hydroxyl groups of the aliphatic polyol (b) is in the range of about 1.05:1 to about 1:1; and, (c) optionally, one or more of acrylamide, methacrylamide, dimethylacrylamide, polyvinyl alcohols, hydroxy functional acrylates, hydroxy functional methacrylates, allyl alcohols, dihydroxy oxamides, dihydroxyamides, dihydroxy piperidines, dihydroxyethyl hydroquinones and mixtures thereof.
