Anionic-Polymerization of Acrylates .9. Lithium-3-Methylpentoxide-3, an Efficient Active-Center Stabilizer in the Anionic-Polymerization of 2-Ethylhexyl and Butyl Acrylates
The article presents preliminary results of the anionic polymerization of 2-ethylhexyl- and butyl acrylates initiated by ester enolate in the presence of Li 3-methylpentoxide-3. Compared with the Li t-butoxide which has been widely used earlier, this alkoxide is a more efficient stabilizer of active centers. Under selectively chosen reaction conditions, polymerizations of both monomers proceed quantitatively with a small extent of the self-termination even at -40 and -20-degrees-C producing polymers with narrow MWD’s.
