Reaction Conditions

Reaction Steps

To 0.11 g (6.68×10−4 mole) 2,2′-bipyridyl and 0.036 g (2.34×10−4 mole) CuBr in a glass tube, were added 0.6 ml (0.55×10−2 mole) IBVE, 1.5 ml (1.65×10−2 mole) methyl acrylate and 0.034 ml (2.34×10−4 mole) 1-phenylethyl bromide under argon atmosphere. The glass tube was sealed under vacuum, and the reaction mixture was warmed at 50° C. for 12 hours. The reaction mixture was then dissolved in THF, and the conversion of MA and IBVE as determined by GC were 100%. The polymer was then precipitated in methanol (three times), filtered, dried at 60° C. under vacuum for 48 h and weighed. The content of IBVE in the copolymer was 25%, and Mn=7860, Mw/Mn=1.90 (Mth=8400). The glass transition temperatures of the product as determined by DSC were at −31.0° C. and 5.6° C.
