Abstract
Abstract A composition having the general formula ##STR1## wherein each R is independently selected from hydrogen, substituted and unsubstituted organic radicals, and radicals of the formula --R 1 NR 2 where R is as previously defined; R 1 is a divalent organic radical; each R 2 is independently selected from substituted and unsubstituted alkyl radicals having at least 12 carbon atoms; each R 3 is an independently selected organic radical having from 1 to 13 carbon atoms; and a, b, and c are, independently, 0 or a positive integer.
