摘　　要：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.The polymerization of acrylonitrile was first studied using (C_9H_7)_2Y(μ-Et)_2AlEt_2 as a single-component catalyst.
