Abstract

With electrochemical polymerization method, polymethylmethacrylate was prepared with iron as electrode, ammonium persulfate as initiator and sodium dodecyl sulfate/OP-10 as composite emulsifying agent. Fourier transform infrared spectroscopy (FT-IR) was used to study its structure. Gel permeation chromatography (GPC) was applied to determine distributions of the molecular size and weight. Effects of the initiator amount, emulsifier dosage and current magnitude on the molecular weight were studied. The preparation condition was optimized using the response surface method (RSM). The optimized preparation conditions of polymethylmethacrylate are as follows: initiator of 3 g, emulsifier of 4 g, and electricity current of 0.2 A, reaction temperature of 30 $^\circ$C and reaction time of 8 h.

Key words： electrochemistry; emulsion polymerization; polymethyl methacrylate (PMMA); molecular weight
