RAFT Inverse Miniemulsion Polymerization of Acrylamide

Abstract: RAFT inverse miniemulsion polymerization is demonstrated for the first time as an alternate way to synthesize hydrophilic polymer latexes. The kinetic behavior of inverse RAFT miniemulsion polymerization of acrylamide is similar to that observed in aqueous RAFT solution polymerization. A water‐soluble initiator provides better control than a lipophilic initiator in inverse RAFT miniemulsion polymerization under the conditions used here.magnified image

“…The induction period occurred for all reactions (with KPS and AIBN) since oxygen enters the reaction medium during the emulsification and homogenization (with Ultra Turrax) steps. The eventual presence of other impurities may also contribute to this induction period (Capek, 2010;Qi 2007, Ouyang et al, 2011b. Though, initial induction periods are usually not desired, their presence does not hamper the purpose of this work, which is to evaluate the ability of NIR spectroscopy to keep track of inverse acrylamide miniemulsion polymerizations despite the presence of disturbances.…”

“…The continuous phase, in which the droplets are dispersed, also contains a nonionic surfactant to retard coalescence (Landfester, 2000). Since monomer droplets/particles are the main polymerization locus and due to their high superficial area, the initiator may either be soluble in the dispersed phase Qi et al, 2007;Kobitskaya et al, 2010) or in the continuous phase (Qi et al, 2007;Kobitskaya et al, 2010;Romio et al, 2013) or in both phases, as in the case of the redox initiation system used by Blagodatskikh et al (2006).…”

“…Como exemplo, Schork et al [52] reportaram que a geração de radicais diretamente no interior das gotas possibilitou um melhor controle da polimerização RAFT de acrilamida em miniemulsão inversa. Entretanto, em alguns sistemas de miniemulsão, o controle da reação é favorecido quando a geração dos radicais ocorre apenas na fase contínua do sistema, uma vez que alguns tipos de iniciadores apresentam mecanismos complexos de partição entre as diferentes fases da miniemulsão, levando a controle menos preciso das condições de reação [51] .…”

“…A Tabela 1 apresenta os estudos publicados até a presente data sobre a produção de polímeros que utilizaram a técnica RAFT em miniemulsão. Conforme revisado, a técnica de polimerização RAFT em miniemulsão já foi adaptada para os principais tipos de monômeros comerciais (como, por exemplo, estireno [28,34,35, , metacrilato de metila [35,54,68,[74][75][76][77][78][79][80] ), sistemas inversos [23,52,[81][82][83][84][85][86] e sistemas contínuos de polimerização [87][88][89] ). Além dos trabalhos citados na P(AM-co-AA) Inverso [83] P(NIPAM-b-PEO) Inverso [82] a Poliestireno (PSt), poli(metacrilato de metila) (PMMA), poli(buitl metacrilato (PnBMA), poli(hidroxietil metacrilato) (PEHMA), poli(butil acrilato) (PnBA), poli(acetato de vinila) (PVAc), Poliacrilamida (PAM), poli(ácido acrílico), poli(2-dimetilamino (metacrilato de etila)) (PDMAEMA), ácido metacrílico (MAA), acrilato de dodecafluoro heptil (DFHA), acrilamida (AM), ácido acrílico (AA), isopopil acrilamida (NIPAM), poli(óxido de etileno) (PEO).…”
