Abstract
Abstract The invention is concerned with novel autoxidizable compositions comprising an unsaturated acid ester of a glycol monodicyclopentenyl ether, a condensation or vinyl addition polymer, a siccative and a volatile stabilizer, which compositions are uniquely adapted to be formulated with high solids and practical viscosity ranges for coating and/or impregnating purposes.
