Aqueous polyurethane dispersions useful for preparing polymers with improved moisture resistance properties

摘要

The present invention is a polyurethane dispersion that can be used to prepare polyurethane polymers which have moisture resistant properties. Moisture resistant polymers of the present invention are obtained by preparing the polymers from a polyurethane dispersion using a prepolymer formulation which includes an aliphatic mono, di or polyhydroxy compound which has an-aliphatic side chain substituent which contains from 5 to 30 carbon atoms.
