Abstract
The process comprises dimerizing methacrylic acid derivatives in the presence of an organic Co(II) glyoxime to produce 2,2-dimethyl-4-methyleneglutaric acid and/or derivatives thereof. Methacrylic acid derivatives include methacrylic acid or derivatives of methacrylic acid. The composition produced by the process comprises a glutaric dimer acid which can be further polymerized to form high molecular weight polymer useful as a binder in protective coatings.
