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.
Claims10
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.
