5/599746

Inventors:

Edward L. Jozwiak - Gibsonia PA
Suryya K. Das - Pittsburgh PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08L 910

US Classification:

260 297DP

Abstract:

A method of preparing resinous vehicles in aqueous medium by addition polymerizing a material having CH. sub. 2. dbd.

Filed:

Jun 22, 1977

Appl. No.:

5/808853

Inventors:

Edward L. Jozwiak - Gibsonia PA
Suryya K. Das - Pittsburgh PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C25D 1306

US Classification:

204181R

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.

International Classification:

G25D 1322
G25D 1310

US Classification:

2041808

Abstract:

In a method for electrocoating an electrically conductive surface serving as an electrode, which method comprises passing an electrical current between the electrically conductive surface to be electrocoated and a counter electrode in contact with an electrodeposition bath comprising a synthetic resin ionically dispersed in an aqueous medium, wherein improvement comprises (a) adding a complexing agent, and then (b) removing at least a portion of the complexing agent along with metals coordinated therewith from the bath.

Appl. No.:

6/162225

Inventors:

Edward L. Jozwiak - Gibsonia PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08L 6310

US Classification:

260 297RP

Abstract:

Polymeric products are prepared by polymerizing in aqueous medium under addition polymerization conditions a dispersed phase of a polymerizable, ethylenically unsaturated monomer or mixture of polymerizable, ethylenically unsaturated monomers in the presence of an at least partially neutralized adduct of a polyepoxide and a primary and/or secondary amine and which contains unsaturation. The polymeric products are useful in water-based coating compositions particularly for use in cationic electrodeposition.
