| 摘要 |
2-Methyleneglutaronitrile is polymerized by heating in benzene at 50 DEG C. for 1 hours and subsequently at 90 DEG C. for 1 hour in the presence of azobisisobutyronitrile.ALSO:2-Methyleneglutaronitrile is prepared by the dimerization of acrylonitrile in the presence of at least one tertiary phosphine. The reaction is preferably conducted in an inert solvent under an inert atmosphere between ambient room temperature and 200 DEG C. and between 0.1 and 100 atmospheres pressure. |
