説明

2-[2-[(tert-Butyldimethylsilyl)oxy]ethoxy]ethyl methacrylate (2) and 2-[2-[2-[(tert-butyldimethylsilyl)oxy]ethoxy]ethoxy]ethyl methacrylate (3) were polymerized anionically in THF at −78 °C for 2−24 h. The anionic initiator systems included 1,1-diphenyl-3-methylpentyllithium/lithium chloride and diphenylmethylpotassium/diethylzinc. The polymerization of novel tert-butyldimethylsilyl-protected oligo(ethylene glycol) methacrylates, 2 and 3, proceeded quantitatively in each case. The resulting polymers possessed the predicted molecular weights based on the molar ratios of monomers to initiators, and narrow molecular weight distributions (Mw/Mn < 1.1). The stability of the propagating carbanion of poly(2) and poly(3) was ascertained by the quantitative efficiencies of the sequential block copolymerizations using tert-butyl methacrylate (tBMA). Well-defined block copolymers, poly(2)-block-poly(tBMA) and poly(3)-block-poly(tBMA), were obtained. The trialkylsilyl protecting groups of poly(2) and poly(3) were qua...
