ABSTRACT:
A process for making metal salt (ionomers) of carboxylic acid-containing mono- and polyether polyol addition products by (1) reacting maleic acid, fumaric acid, itaconic 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 to form a carboxylic acid group-containing addition product and (2) neutralizing said addition product with a sufficient amount of metal ions selected from the group consisting of metals from Groups 1a, 2a, 8, 1b and 2b of the Periodic Table to convert at least about 10% of the carboxylic acid groups to ionomeric salt groups. These ionomers may be then changed into useful polyurethane elastomers by reaction with organic polyisocyanates.
