Abstract
Compounds are disclosed having the structure ##STR1## wherein A represents arylene or carboxyl; R represents H or CH.sub.3 ; and R.sub.2 and R.sub.3, each independently, represents alkylene of 2 to 7 carbon atoms. The compounds are useful in making curable polyurethane, polyesters and vinyl polymers.
