Abstract
Described are novel acrylic monomers, homopolymers and copolymers prepared therefrom, and electrophoresis gel media prepared by crosslinking certain copolymers of the invention by a crosslinking reaction that does not involve a free-radical vinyl addition mechanism.
Claims4
An element for electrophoresis which comprises a crosslinked polymer which, before crosslinking, conforms to the structure ##STR11## wherein --A-- represents recurring units derived from one or more polymerized acrylamide monomers, R.sup.1 is hydrogen or methyl, R.sup.2 is a haloacetamido group, L is ##STR12## alkylene, arylene, a divalent heteroatom, or a combination of ##STR13## alkylene, divalent heteroatom, and/or arylene, Z is a divalent heterocyclic group having from 5 to 7 nuclear carbon and heteroatoms;
- --B-- represents recurring units derived from any other polymerized vinyl monomer;
- and x, y, and z represent weight percents of the recurring units, x being about 50-90 weight percent, y being about 1-50 weight percent, and z being about 0-45 weight percent.
