Method for producing polymerizable monomers containing a sulphate group |
| abstract |
A method for producing sulphatoalkyl acrylates or methacrylates having the general formula; <IMAGE> where R1 is H or CH3, R2 is one or more alkoxylate groups each of which has from 1 to 4 carbon atoms, comprises reacting a hydroxy alkyl acrylate or methacrylate having the formula; <IMAGE> where R1 and R2 are as defined above, with chlorosulphonic acid at a temperature of less than 20 DEG C. to form the acid ester. Salts of the acid ester may be produced by reaction with a basic metal salt, ammonium salt or quaternary ammonium salt. |
