摘要：

Radical homopolymerization of poly(ethylene oxide) (PEO) macromonomers carrying n-dodecyl or n-octadecyl group as the omega-end and p-vinylbenzyl or methacryloyl group as the alpha-end was carried out in benzene, cyclohexane, and water. The micellar polymerization in water with an exceptionally high rate was confirmed as previously found, while the polymerization in cyclohexane was considerably faster than in benzene. The significant effects of the omega-alkyl groups and the PEO chain lengths on the polymerization rate were observed in cyclohexane, suggesting formation of some loosely organized, inverse micelles of these amphiphilic macromonomers, but not in benzene.
