ABSTRACT:
Disclosed is a process for making carboxylic acid-containing mono- and polyether polyol addition products by reacting maleic acid, fumaric acid, or mixtures thereof with at least one polyhydroxy-containing mono- or polyether compound (e.g. a polyether diol or triol) in the presence of a peroxy-type free radical initiator. Also disclosed are the processes of making polyurethane prepolymers and aqueous polyurethane dispersions from these carboxylic acid-containing mono- and polyether polyol addition products and processes for using these dispersions in coatings, adhesives and other useful products.
