✦ Synopsis

Polymerization of methyl methacrylate using H20, with poly(ethylene oxide) having xanthate groups, was carried out to yield methyl methacrylate-ethylene oxide block copolymers. Principal parameters affecting the synthesis were examined. Block copolymers were characterized by spectroscopic methods.

The acidic aqueous emulsion polymerization of methyl methacrylate, initiated by ceric ammonium nitrate<lodecyl poly(ethylene oxide) redox system at 30 Β°, was studied. The polymerization was characterized by a pronounced gel effect and showed deviations from the Smith-Ewart theory established for sty
