    摘要： The present invention provides for amino-crosslinkable coating formulations based on a mixture of a di or polyhydroxy functional polymeric component selected from the group consisting of diesters, polyesters, alkyd polymers, acrylic polymers and polycarbonate polymers, a methylol (alkoxymethyl) amino crosslinking agent and a bis-aromatic polyhydric phenol component having the structure of formula I: ##STR1## wherein X is selected from the group consisting of carbon to carbon covalent bond, oxygen, sulfur, --S--S--, --CO--, --SO--, --SO.sub.2 -- and a divalent organic radical having a molecular weight less than about 400, and wherein Y is independently selected from the group consisting of hydrogen, halogen, C.sub.1 to C.sub.4 alkyl and C.sub.1 to C.sub.4 alkoxy.

    摘要： The present invention is directed towards a process for preparing non-liquid crystalline phenol-terminated diester compositions characterized by the structure of formula 1: ##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 an 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 his 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.The invention is also directed to a single stage direct esterification or multi stage esterification processes for producing the aforementioned diesters of formula 1 either with or without the use of esterification catalysts, and is particularly directed to such processes for preparing diesters of reduced color using a low temperature process in combination with catalyst systems containing a phosphorous acid or derivative thereof.
