Abstract
Official abstract text for this publication.
The present invention provides poly(ureaurethane)s including a reaction product of components comprising: (a) at least one isocyanate functional ureaurethane prepolymer comprising the reaction product of: (1) at least one isocyanate functional urethane prepolymer comprising the reaction product of: (i) a first amount of at least one polyisocyanate selected from the group consisting of polyisocyanate trimers and branched polyisocyanates, the polyisocyanate having at least three isocyanate functional groups; and (ii) a first amount of at least one aliphatic polyol; and (2) water, to form an isocyanate functional ureaurethane prepolymer; and (b) a second amount of at least one polyisocyanate and a second amount of at least one aliphatic polyol; compositions, coatings and articles made therefrom and methods of making the same.
First claim
Opening claim text (preview).
What is claimed is: 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: (1) at least one isocyanate functional urethane prepolymer consisting of the reaction product of: (i) one…
