A composition comprising compounds of the formula ##STR13## wherein n=0;
- y=0 or 1;
- wherein X is a divalent hydrocarbyl group selected from the group consisting of ##STR14## when y=0, and ##STR15## when y=1 wherein R.sup.1 is H or a hydrocarbon based group;
- each R.sup.3 is independently H or hydrocarbyl;
- each R.sup.4 is independently a divalent hydrocarbylene group;
- R.sup.5 is H or hydrocarbyl;
- each of R.sup.6, R.sup.7 and R.sup.8 is independently H or a hydrocarbon based group, and T is --OH.
