| 摘要 |
The present invention relates to novel organic compounds and polymers which are adducts of sulfomaleic anhydride, its isomers or derivatives, with unsaturated organic molecules wherein the novel products are produced by contacting sulfomaleic anhydride with an unsaturated organic compound to form the novel product. In particular, the unsaturated organic molecule can be a hydrocarbon polymer ranging in molecular weight from about 500 to about 10,000,000. The resultant adduct of sulfomaleic anhydride and the unsaturated hydrocarbon can be further reacted with a polyamine, which will neutralize the sulfonic acid group, as well as covalently bond to the copolymer by reacting with the anhydride group. The amine salt can be converted to a metal salt by reaction with metallic bases. The compounds and polymers are used as thermoplastic elastomers, disbursements, viscosity index improvers, drilling mud viscosifiers, and deflocculants, amongst other applications. |
