- W2003222568 abstract "TH~ fact that there are comparatively few papers on homogeneous polymerization of acrylonitrile (AN) induced by anionic catalysts can be explained by the very limited choice of suitable solvents, inert to the catalysts used. In a study of the polymerization of AN in dimethylformamide (DMF) catalysed by sodiumdiphenyl, Tsukamote [1] states that sodiumdiphenyl does not react with the solvent at temperatures below --40 °. Zilkha and his collaborators [2-4] in studying the polymerization of AN under the influence of lithium butyl, C4H~Li, using DMF as the medium or as an electronating additive, did not take account of the possibility of reaction occurring between C4H~Li and DMF. Dimethylformamide reacts vigorously with alkali metal alkyls or aryls however. The products of the reaction after decomposition with water are aldehydes and amines [5]. We have been able to demonstrate that even at --70 ° D1KF reacts instantaneously with C4H~Li, and under carefully controlled reaction conditions the primary product is lithium butyl(dimethylamino)carbinolate [6]" @default.
