Abstract

A polymerizable amino acid compound of the formula: ##STR1## 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 bearing at least one hydroxyl and optionally having --O-- or --COO-- in the alkyl chain, R.sub.5 is hydrogen or C.sub.1 -C.sub.20 alkyl optionally bearing at least one hydroxyl and optionally having --O-- or --COO-- in the alkyl chain, or when R.sub.4 and R.sub.5 are taken together with the nitrogen atom to which they are attached, they represent a nitrogen atom containing heterocyclic group, 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 is highly soluble in water or organic solvents without any acidic or basic substance and can be introduced into the molecule of high molecular compounds.

Dependent claims

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.
