| abstract | 1428941 Anionic polymerization of methacrylates CESKOSLOVENSKA AKADEMIE VED 6 May 1974 [7 May 1973] 19847/74 Heading C3P Esters of methacrylic acid are polymerized anionically using as initiator an alphalithiosubstituted carboxylic acid ester. The process is carried out in an aromatic hydrocarbon or aliphatic ether at - 70‹ to + 50‹ C. The initiator may be prepared in situ from a substituted lithium amide and the appropriate carboxylic ester or from an organolithium compound, secondary amine and an appropriate carboxylic ester. A lithium alkoxide may also be present in the polymerization. In typical examples, methyl- or n-octyl methacrylate are polymerized in toluene using ethyl-α-lithioisobutyrate or mixtures thereof with lithium t-butoxide or (-)-menthoxide, or in situ initiator mixtures of n - butyl lithium / diisopropylamine / ethylisobutyrate or di-t-butyl-α,α<SP>1</SP>,α<SP>1</SP>-trimethylglutarate /N-lithium diisopropylamide. |
