添加适量的对叔丁基苯酚钠、2，6-二叔丁基对甲基苯酚钠、2-甲基萘酚钠或季铵盐可以显著提高二(叔丁基环戊二烯基)钕甲基配合物催化丙烯腈聚合的活性．考察了由(C4H9)4NBr与[(Bu℃p)2NdMe]2组成的催化体系中季铵盐用量、聚合温度、催化剂用量、单体浓度及溶剂对聚合活性的影响．当(C4H9)4NBr与 [(Bu℃p)2NdMe]2的摩尔比等于2，催化剂用量为每克单体2．0×10-5mol，40℃，聚合2 h，转化率可达[(Bu℃p)2NdMe]2的摩尔比等于2，催化剂用量为每克单体2．0×10-5mol，40℃，聚合2 h，转化率可达65．4％．
The polymerization of acrylonitrile catalyzed by [(ButCp)2NdMe]2/quarternary ammoniumsalt (sodium phenolate、 sodium naptholate) was first studied. The catalytic activity of [(But-Cp)2NdMe]2(Cat) was greatly increased by adding quarternary ammonium salt, sodium phenolate orsodium naptholate, such as CH3 (CH2)15NBrMe3, Me4NBr, (C4H9)4NBr, 2,6-di-Bu1/2-4-MeC6H2ONa,4-ButC6H4ONa and (2-MeC10H6ONa). The polymerization conditions were investigated, including theeffects of the mole ratio of (C4H9)4NBr to Cat , the amount of Cat , monomer concentration,polymerization temperature and solvent. The conversion of acrylonitrile was as high as 65. 4% at thepolymerization conditions: [(C4H9)4NBr]/[Cat]=2, [Cat]=2. 0X 10-5 mol/g, x(M)=50%, 40 ℃,toluene, 2 h.
