Abstract
Abstract A method of preparing resinous vehicles in aqueous medium by addition polymerizing a diene with a partially neutralized reaction product of an unsaturated carboxylic acid or anhydride and a drying oil is disclosed. The resinous vehicles are prepared in the presence of an oil-soluble free radical polymerization catalyst and have properties necessary for electrodeposition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
A process for preparing a resinous vehicle suitable for electrodeposition which comprises: A. addition polymerizing a diene, in the presence of an oil-soluble free radical polymerization catalyst, in aqueous medium with B. an at least 25 percent neutralized reaction product of: 1. not more than about 45 percent by weight of an unsaturated dicarboxylic acid or its anhydride with 2. at least about 55 percent by weight of a drying oil which has an iodine value of about 90 and above.
Claim 2
Dependent Claim
81 words
A process for preparing a resinous vehicle suitable for electrodeposition which comprises: A. addition polymerizing a diene, in the presence of an oil-soluble free radical polymerization catalyst, in aqueous medium with B. an at least 25 percent neutralized reaction product of: 1. not more than about 45 percent by weight of an unsaturated dicarboxylic acid or its anhydride with 2. at least about 55 percent by weight of a drying oil which has an iodine value of about 90 and above.
Claim 3
Dependent Claim
11 words

Claim 4
Dependent Claim
27 words
