Process for the production of methacrylic acid and its derivatives and polymers produced therefrom |
| abstract |
A process for the production of methacrylic acid by base-catalyzed decarboxylation of at least one dicarboxylic acid selected from itaconic acid, citraconic acid or mesaconic acid or mixtures thereof is described. Decarboxylation is performed at a temperature in the range of 100 to 199 ° C. A method for preparing a polymer or copolymer of methacrylic acid or a methacrylic ester is also described. |
