Abstract
Aqueous polyurethane dispersions prepared from chain extended polyurethane prepolymers which are the reaction product of a di- or polyisocyanate, a polyol component containing, in major part, a polyoxypropylene diol having an unsaturation of 0.020 meq/g or less, and a reactive dispersing aid, are suitable for preparing polyurethane films with greater softness and elasticity than similar films prepared from PTMEG, and greater tensile strength and elasticity than polyoxypropylene diols having conventional levels of unsaturation.
