Abstract
A one-step process for synthesizing water soluble self-curing polyurethanes is achieved by co-reacting certain monomers under controlled conditions to form a blocked, water soluble polyurethane which can be subsequently dispersed in water. The polyurethane polymer is substantially free of high molecular weight hydrocarbon chains and essentially comprises all polyurethane units and is adapted to self-cross link upon being subjected to heat. The polymer is particularly suitable for producing polyurethane protective coatings which exhibit substantially increased film hardness, abrasion resistance, as well as other desirable film integrity properties.
