Реферат: Disclosed is a two-component curable polymeric system having increased viscosity. One component contains a homogeneous blend of a polyisocyanate and a homopolymer or copolymer of vinyl acetate. This component has a higher viscosity than the polyisocyanate alone, thereby increasing the viscosity of the two-component curable system. The other component of the two-component curable system is a composition containing an isocyanate reactive component. The polyisocyanate and the isocyanate reactive component react together ("cure") to form a polymer. Typically, but not always, the isocyanate reactive component is a polyol or polyamine that is capable of reacting with the polyisocyanate, thereby forming a polyurethane (polyol) or polyurea (polyamine).
