文摘The polymerization of acrylonitrile was first studied using (C9H7)2Y(μ-Et)2AlEt2 as a single-component catalyst. The catalytic activity could be greatly increased when PhONa was added to the catalyst in amount of n(PhONa)/n(Cat)=3. A mechanism related to the polymerization initiation of AN is proposed.
