ABSTRACT:
The present invention is directed towards a mixture of phenol terminated diesters and an amino crosslinking agent. The diesters are characterized by a structure consisting of ##STR1## wherein R is an aliphatic divalent hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, provided however that R contains at least about 8 carbon atoms when n is 0 and p is 0, R.sub.1 is an aliphatic or cycloaliphatic hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, R.sub.2 is a aliphatic, aromatic or a mixture of aliphatic and aromatic hydrocarbon radicals having from 2 to 40 carbon atoms, A is divalent aromatic radical selected from the group consisting of phenylene, naphthylene or bis phenylene, p is 0 or 1, n is 0 or an integer ranging from 1 to about 40, provided however, that p is 0 when n is 0 and p is 1 when n is an integer and ##STR2## wherein q is an integer ranging from 1 to about 40, n is 0 or an integer ranging from 1 to about 40 and A, R.sub.1 and R.sub.2 are as defined above.
