| Research Abstract |
The polymerization kinetics of various controlled/living radical polymerization(CLRP) inside submicron particles(<200nm) are investigated. The polymerization rates of CLRPs are conveniently represented by a simple formula in a unified manner, which clarifies the differences from the bulk polymerization systems. The differences result from two important factors unique to nano-sized reaction loci,"single-molecule-concentration effect" and "statistical concentration variation effect". The threshold particle diameters below which the polymerization rate becomes larger/smaller than that for bulk polymerization are successfully represented by simple equations.
