Abstract
A method for polymerizing olefinically unsaturated carboxylic acids containing at least one activated carbon to carbon olefinic double bond and at least one carboxyl group in mineral spirits in the presence of a free radical forming catalyst and at least two surface active agents having HLB values of less than 10, a sorbitan ester with a glycerol or alkylene glycol ester and a long chain alcohol, to provide fluid, high total-solid dispersions of polymer in mineral spirits.
