  摘要：

  通过硅酸酯化方法制备的简单烷基次膦酸盐可以在类似巴比尔的条件下与丁基锂在 -78 °C 下烷基化，然后升温至室温。该方法仅限于反应性更强的亲电子试剂，例如烯丙基溴化物和烷基碘化物。使用这些亲电子试剂，通常以简单的方式获得高产率的 H-次膦酸酯。

  Alkyl-H-phosphinic acid alkyl esters are synthesized in 65–71% yield via chemoselective reaction of alkyl bromides with available alkyl-H-phosphinic acids (60–65 °C, Et3N). The latter are prepared, in turn, by direct phosphorylation of alkyl bromides with red phosphorus under phase-transfer conditions.

  A conjugated diene compound prepolymer solution useful for the production of a vinyl aromatic compound high impact polymer material is produced by a process in which a prepolymerization mixture is prepared from 1 to 70 parts by weight of a conjugated diene compound and 30 to 99 parts by weight of a vinyl aromatic compound, and is prepolymerized at 0°C to 150°C in the presence of a prepolymerization catalyst which can cause the conjugated diene compound to be selectively polymerized but is substantially not effective for the polymerization of the vinyl aromatic compound to an extent such that the conjugated diene compound and the vinyl aromatic compound are prepolymerized at degrees of conversion of the conjugated diene compound at least 50% and 10% or less, respectively, and the resultant prepolymer solution is further polymerized by a radical or anionic polymerization method so that the vinyl aromatic compound is polymerized with the conjugated diene compound prepolymer.
