Abstract

New dual stimuli-responsive (thermo- & pH-) polymers were successfully synthesized through an atom transfer radical mechanism in aqueous media. N-Isopropylacrylamide (NiPAM) ([N]) as a precursor of temperatureresponsive moiety and sulfonamide-modified styrenic monomer and methacrylamide ([S]) were employed for the synthesis of the smart copolymers. The molar ratio of NiPAM to sulfonamide composed of the polymer backbone played an important role in the control of the phase transitional behavior of the formed block polymers. When the composition ratio of [S]/[N] decreases from 1/1 to 1/2, the dual stimuli-responsive phase behavior was clearly observed. Another important factor for the control of the phase morphology was to obtain the reactivity ratios, r₁ and r₂, of the two monomers. In this study, Cu(I)-catalyzed copolymerization of sulfadimethoxinyl methacrylamide (MASX; M₁) and NiPAM (M₂) as the precursors of smart materials yielded r₁ = 8.046 and r₂=1.572, leading to the production of a gradient type of copolymer in aqueous media.
