The objects of research are synthesized new polymeric surfactants (poly-surfactants)  copolymers of N, N-dimethyl-N, N-diallylammonium chloride with N  [(3-trimethylamino) propyl]methacrylamide (DMDAAH TMAPMA). The molar composition and structure of the synthesized copolymers were proved by methods of conductometric titration, FTIR and NMR spectroscopy.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>radical copolymerization</kwd><kwd>copolymer</kwd><kwd>flocculate</kwd><kwd>structure creator</kwd><kwd>biocidal material</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>радикальная сополимеризация</kwd><kwd>сополимер</kwd><kwd>флокулянт</kwd><kwd>структурообразователь</kwd><kwd>биоцидный материал</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кульский Л.А., Строкач П.П.
