Abstract
The present invention comprises a novel composition of matter having the general formula: ##STR1## wherein R.sub.1 is H or an alkoxide of from 5 to about 20 carbon atoms; x is an integer of from about 8 to 22 when R.sub.1 =H and from about 2 to 5 when R.sub.1 is an alkoxide; R.sub.2 is selected independently from H, (CH.sub.2 CH.sub.2 O).sub.m H, and (CH.sub.2 CH(CH.sub.3)O).sub.m H; R.sub.3 is selected independently from H, (CH.sub.2 CH.sub.2 O).sub.n H, and (CH.sub.2 CH(CH.sub.3)O).sub.n H; m and n are integers from 1 to 50; and y and z are integers from 2 to 10.
