Preparação de copolímeros à base de 2-vinilpiridina com propriedades bactericidas

Abstract: Recebido em 14/4/10; aceito em 17/11/10; publicado na web em 18/2/11 SYNTHESIS OF COPOLYMERS BASED ON 2-VINYLPYRIDINE WITH ANTIBACTERIAL PROPERTIES. We report the development of two copolymers based on 2-vinylpyridine, styrene and divinylbenzene (2Vpy-Sty-DVB) with different porosity degrees. The copolymers were subsequently quaternized with methyl iodide. To prepare charge transfer complexes, the unmodified copolymers and their derivatives quaternized with methyl iodine were impregnated with iodine. The antib… Show more

“…Dentre os grupos biocidas mais estudados, destacam-se os sais de amônio e fosfônio quaternários [1,7,8,11,12,16,[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] , os complexos de transferência de carga envolvendo grupos amônio quaternário e iodo [10,12,13,[32][33][34][35][36][37][38][39][40][41][42][43][44]47,[63][64][65][66] , as N-haloaminas [7,47,[67][68][69][70][71]…”

“…Os polímeros contendo grupos amônio, fosfônio e piridínio são indiscutivelmente os biocidas poliméricos mais explorados na literatura [47] . A ação biocida dos outros grupos catiônicos tem sido pouco explorada [1,7,12,15,16,[47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] . O mecanismo mais aceito de ação biocida dos polímeros poliquats é baseado na interação destrutiva entre os grupos quaternários e a parede celular e/ou membrana citoplasmática.…”

“…An ethanolic solution of HCl (1 mol L -1 ) and acrylonitrile (5.95 mol) was added and the resulting mixture was refluxed for 3 days. The beads were filtered, washed with hot water (70 °C, 500 mL) and acetone (250 mL) and dried at atmospheric pressure for 24 hours at 60 °C [20] .…”
