“…To our knowledge, this is the first time such a synthesis using nitroxide-mediated polymerization is reported. Lokaj et al [41] attempted to synthesize a block copolymer of styrene and DMAEMA using TEMPO-terminated poly(styrene) macroinitiators. However, conversion stopped increasing after 2 h of reaction and the final copolymer contained only about 40 mol% DMAEMA.…”

“…6 This idea has special interest on the synthesis of block copolymers, because the control of morphology in block copolymers has became important in the design of new physical properties through a structure-property relationship. 7,8 The synthesis of styrene-b-methyl methacrylate, p(S-b-MMA), 9 styrene-b-2-dimethylamino ethyl methacrylate, p(S-b-DAMA), 10 styrene-bstyrene-co-butyl methacrylate, p(S-b-S-BMA), 11 and styrene-b-butyl methacrylate, p(S-b-BMA) 12 have been reported. In all the cases polystyrene-TEMPO end capped has been used as the macroinitiator.…”

“…Os copolímeros em bloco de monômeros ordinários obtidos via radicais livres mediados por nitróxidos estáveis têm sido anunciados na literatura desde 1994 [39][40][41][42][43][44][45][46][47][48][49][50] . A obtenção de um copolímero em bloco LC contendo um segmento amorfo e um segmento LC empregando essa técnica de polimerização foi um trabalho pioneiro do IMA.…”

“…A potencialidade de síntese de copolímeros em bloco LC empregando o mecanismo de polimerização via radicais livres por transferência atômica catalisada por cobre foi também investigada [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] . Essa técnica começou a ser mundialmente explorada para obtenção de copolímeros em bloco não-LC, a partir de 1995, na polimerização de monômeros estirênicos e acrílicos com bom controle estrutural.…”
