Process for preparing stable polyurethane latices

摘要

Stable polyurethane polymer latices are obtained by incorporating specified amounts of polyethylene glycol into the backbone of various polyurethane polymers. The polyurethane latices are non-ionic but can assume an anionic or cationic character by the addition of anionic or cationic emulsifying or surface active agents. The latices have wide utility, for example, as adhesives, coatings, textile sizes, binders, and in molding applications.
