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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
A soluble linear addition polymer obtained (1) by anionic polymerization or (2) by solution polymerization or aqueous emulsion polymerization using a free radical initiator, adapted to be cured by autoxidation with a siccative, of a compound having the general formula: ##STR3## wherein R' is H or CH 3 and R" is selected from the groups consisting of (a) Alkylene groups having 2 to 6 carbon atoms and (b) Oxaalkylene groups having 4 to 12 carbon atoms and having one or more oxygen atoms joining distinct segments of the alkylene chain each of at least 2 carbon atoms length extending between oxygen atoms of the alkylene group.
Claim 2
Dependent Claim
106 words
A soluble linear addition polymer obtained (1) by anionic polymerization or (2) by solution polymerization or aqueous emulsion polymerization using a free radical initiator, adapted to be cured by autoxidation with a siccative, of a compound having the general formula: ##STR3## wherein R' is H or CH 3 and R" is selected from the groups consisting of (a) Alkylene groups having 2 to 6 carbon atoms and (b) Oxaalkylene groups having 4 to 12 carbon atoms and having one or more oxygen atoms joining distinct segments of the alkylene chain each of at least 2 carbon atoms length extending between oxygen atoms of the alkylene group.
