Abstract
Abstract Hydrocurable compositions of a hydroxy(polyalkylenecarbonyloxy)alkyleneoxazolidine and a polyfunctional isocyanate are disclosed. The compositions are useful in forming films, paints, coatings, fibers, seamless flooring, coatings, impregnants and adhesives for natural and synthetic materials. The compositions are prepared by treating a hydroxy(polyalkylenecarbonyloxy)alkyleneoxazolidine with a polyfunctional isocyanate or by treating a bisoxazolidine isocyanate prepolymer with a polyfunctional isocyanate.
