摘要：
The present invention provides poly(ureaurethane)s including a reaction product of components comprising: (a) about 1 equivalent of at least one polyisocyanate; (b) about 0.1 to about 0.9 equivalents of at least one branched polyol having 4 to 18 carbon atoms and at least 3 hydroxyl groups; (c) about 0.1 to about 0.9 equivalents of at least one aliphatic diol having 2 to 18 carbon atoms; and (d) at least one amine curing agent, wherein the reaction product components are essentially free of polyester polyol and polyether polyol; compositions, coatings and articles made therefrom and methods of making the same.
