Abstract

Atom transfer radical polymerization of metliyl methaciylate (MMA) was studied at 25 t in emulsion with CuX/phenanthroline (phen) as catalyst, ethyl 2-bromoisobutyrate (EBiB) as initiator, and sodium lauryl sulfonate as surfactant, respectively. The controllability of the polymerization was further improved through the addition of deactivator CuBr_2/phen into the polymerization system or by "halogen exchange reaction" between CuCl/phen and EBiB. Increase of the partition of CuBr/phen in MMA phase with decreasing the temperature of polymerization was observed by means of UV measurements, giving rise to the fast polymerization of MMA with good controllability at room temperature.

Key words: CUPROUS COMPOUNDS, PHENANTHROLINE, ALKYLSULFONATE, EMULSIFYING AGENTS, MMA, UV
