Synthesis of 6- and 7-oxo poly(vinyl ester)s and their evaluation



Long chain vinyl esters of 6- and 7-oxoaliphatic acids are synthesized as intermediate monomers for the preparation of poly 6-oxo and 7-oxo vinyl esters. These comblike polymers have wide applications as fluidity improvers. Detailed characterization of all the intermediates is done by IR, PMR, and MS for the first time. Their evaluation is done on high waxy Bombay high crude.
