✦ Synopsis

brief report is given of the method of intermittent illumination and of the rotating sector polymerization instrument built in our laboratory. The solvent dependence of chain propagation and termination rate constants was investigated for the polymerization system styrene-benzene at 50. The observed solvent dependence was found to be caused by the chain propagation step, in accordance with the hot radical theory.

Molecular mass distribution was investigated for the polymerization of styrene initiated by AIBN at 50 in the presence of various solvents. Two types of solvents were chosen; in one, there is no chain transfer to solvent (Bz, DMF) whereas in CC14 the chain transfer should be considered. The molecula

A~tract--The present paper reports an investigation on the "pseudo-living'" radical chain propagation process in the case of the styrene polymerization initiated by benzopinacolates. Two steps were observed, as in earlier reported investigations. Oligomers were formed first at low monomer conversion

## Abstract Styrene was polymerized by intermittent photoinitiation (at a constant sector speed and a light to dark ratio of 1:5) in microemulsion. The molecular weight distribution was measured by size‐exclusion chromatography and turned out to be extremely well structured. When the points of infl
