説明

<jats:title>Abstract</jats:title><jats:p>Anionic polymerizations of 2,2,2‐trifluoroethyl acrylate <jats:bold>(1a)</jats:bold>, 2,2,2‐trifluoroethyl methacrylate <jats:bold>(1b)</jats:bold>, 2,2,2‐trifluoro‐1‐trifluoromethylethyl acrylate <jats:bold>(2a)</jats:bold> and 2,2,2‐trifluoro‐1‐trifluoromethylethyl methacrylate <jats:bold>(2b)</jats:bold> were carried out with several ate complexes as initiators. LiZnC<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>2</jats:sub> was found to initiate the polymerization of methacrylates to produce the corresponding polymers in high yields. LiAlC<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>3</jats:sub> also showed appreciably high initiation reactivity for the polymerization of methacrylates. Ate complexes containing alkaline earth metals, except magnesium, were inactive for the polymerization of these four monomers. Polymers of <jats:bold>2a</jats:bold>, which are generally not obtained with typical anionic initiators such as butyllithium or organomagnesium compounds, were produced with LiAlC<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>3</jats:sub> and MgZn(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub> as initiators, though the yield of the polymers was only 40%.</jats:p>
