SummaryMixed polyvinyl esters of acetic acid and higher fatty acids can be made by ester interchange between polyvinyl acetate and fatty esters. Their properties indicate that some of these products merit attention as materials for use in the drying oil industries. Because of their enhanced drying qualities and greater tolerance of the presence of saturated acid components, in comparison with the corresponding glycerides, they potentially broaden the range of fatty materials utilizable as drying oils.
