Abstract

Abstract Radical copolymerizabilities of poly(ethylene glycol) allenyl methyl ether ( 2a and 2b, the number average molecular weight ( M n) = 390 and 590, receptively) were evaluated by the copolymerization with styrene monomer ( St). The relative reactivities of macromonomers have been decreased as the length of the oxyethylene side chains in the macromonomer increased, and were estimated to be r 1 = 2.5 ± 0.1, r 2 = 0.96 ± 0.2 for 2a and r 1 = 1.4 ± 0.1, r 2 = 2.4 ± 0.3 for 2b.
