In one aspect, compounds, methods of using them, compositions comprising such compounds, and uses of such compositions . These objects, and others which will become apparent from the following disclosure, are achieved by the present invention which comprises in one aspect compounds of the formula ##STR1## wherein R is alkyl, cycloakyl, aryl, substituted aryl, alkaryl optionally substituted on the aryl portion or aralkyl optionally substituted on the aryl portion, R having up to 20 carbon atoms and is optionally branced, and A is (CH.sub.2).sub.p, (CH.sub.2).sub.q --O--(CH.sub.2).sub.r, or (CH.sub.2).sub.q --S--(CH.sub.2).sub.r, wherein p=2 to 8, q=1 to 8, and r=1 to 8. R.sub.1 =--(CH.sub.2).sub.m --,--(CH.sub.2 CH.sub.2 --O).sub.n --CH.sub.2 CH.sub.2 --, or --(CH.sub.2 CH.sub.2 CH.sub.2 --O).sub.n --CH.sub.2 CH.sub.2 CH.sub.2 --. In another aspect, the invention comprises polymers of the formula ##STR2##
Process comprising polymerizing a monomer ##STR10## wherein R.sub.1 =--(CH.sub.2).sub.m --, --(CH.sub.2 CH.sub.2 --O).sub.n --CH.sub.2 CH.sub.2 --, or --(CH.sub.2 CH.sub.2 CH.sub.2 --O).sub.n --CH.sub.2 CH.sub.2 CH.sub.2 -- in which m=7 to 24, n=1 to 10;
Composition comprising polymer produced by the process of claim 3 having utility as an antimicrobial agent.
