Abstract
The Cu(0)-mediated reversible deactivation radical polymerization of N,N′-dimethylaminoethyl acrylate in DMSO and IPA at ambient temperature using Cu(0) wire is investigated. Tetra- and octafunctional initiators were utilized to facilitate the synthesis of well-defined PDMAEA star homo and block copolymers with a range of molecular weights (Mn ∼ 5000–41 000 g mol–1). Both solvents demonstrated to be excellent media for the controlled polymerization of DMAEA, yielding narrow molecular weight distributions (Đ ∼ 1.1) when the reactions were ceased at ∼40% conversion. Interestingly, at high conversions (typically >55%) high and low molecular weight shoulders were evident by SEC when DMSO and IPA were used, respectively, suggesting a large extent of termination and/or side reactions at prolonged reaction times. Nevertheless, high end group fidelity could be maintained when immediate precipitation of the polymers (at lower conversion) was performed, yielding low dispersed P(DMAEA-b-MA) star block copolymers (Đ ...
