Abstract
The title compounds are of the formula: ##STR1## wherein R is a chemical bond, oxygen, sulfur, alkylene or alkylidene; W is hydrogen or a (--CR.sub.1 R.sub.2 --CR.sub.3 R.sub.4 --NHR.sub.5) group with the proviso that at least two W groups are (--CH.sub.1 R.sub.2 --CR.sub.3 R.sub.4 --NHR.sub.5) groups; wherein R.sub.1 -R.sub.4 are each independently hydrogen, lower alkyl or hydroxy-substituted lower alkyl; R.sub.5 is hydrogen or a ##STR2## group, wherein R.sub.6 is hydrogen, hydrocarbyl or inertly substituted hydrocarbyl; X, Y and Z are each independently inert substituents; m and p are each independently integers of from zero to four, inclusive; n is an integer of from zero to three, inclusive; q is a number of from zero to about ten; and M is alkylene or alkylidene. They are conveniently prepared by reacting a 2-oxazoline of the formula: ##STR3## with a polyhydric polyphenol of the formula: ##STR4## in the presence of certain metal salt catalysts (e.g. zinc acetate).
