Claims
- 1. A process for preparing a polymerizable amino acid compound of the formula: ##STR28## wherein R.sub.1, R.sub.2 and R.sub.3 are each hydrogen or methyl, R.sub.4 is C.sub.1 -C.sub.20 alkyl optionally substituted with at least one hydroxyl and optionally substituted with --O-- or --COO-- in the alkyl chain, R.sub.5 is hydrogen or C.sub.1 -C.sub.20 alkyl optionally substituted with at least one hydroxyl and with or without --O-- or --COO-- in the alkyl chain, R.sub.6 is an alkylene group having not more than 6 carbon atoms and A is --COO-- or --SO.sub.3 --, provided that when R.sub.4 is C.sub.1 -C.sub.20 alkyl, R.sub.5 is not hydrogen which comprises reacting a benzyl halide of the formula: ##STR29## wherein X is chlorine or bromine and R.sub.1, R.sub.2 and R.sub.3 are each as defined above with an amino acid compound of the formula: ##STR30## wherein R.sub.4, R.sub.5, R.sub.6 and A are each defined above under basic conditions at a temperature of 0.degree. to 150.degree. C. in the absence or presence of a solvent.
- 2. The process according to claim 1, wherein the solvent is alcohol, ethylene glycol monoalkyl ether, dimethylformamide, dimethylsulfoxide or water, or a mixture thereof.
- 3. The process according to claim 1, wherein the reaction is carried out at a temperature of 0.degree. to 150.degree. C.
- 4. The process according to claim 1, wherein the reaction is carried out under an atmospheric or elevated pressure.
- 5. The process according to claim 1, wherein the reaction is carried out for a period of 10 minutes to 48 hours.
