| Abstract: | 1.5-Diphenyl-3-(p-methacryloyloxymethylphenyl) verdazyl (I), 1.5-diphenyl-3-(p-methacryloyloxyphenyl) verdazyl (II), and 1.5-diphenyl-3-(p-acryloyloxymethylphenyl) verdazyl (III) were synthesized and anionically polymerized with n-butylmagnesium bromide or sodium naphthalene as an initiator to dark green polymers of a molecular weight of about 2300. III was polymerized with a catalytic amount of initiator, while I needed more initiator than the molar equivalent of the monomers suggesting the formation of intermediate metal salts of monomers and subsequent polymerization of the salts. More reactive double bond of III polymerized directly without the formation of the salt between stable free radical and organometallic compounds. Polymeric verdazyls contained up to 68% stable free radical. |
