Polymerization experiment was completed in an autoclave (1 L) using industrial by-product mixture of decene andα-olefins as raw materials and isopropyl alcohol as initiator over BF3 catalyst. The effects of the species and amount ofα-olefins, reaction pressure, reaction temperature, reaction time and the types and amount of initiators on the polymerization process were investigated. The results showed that the poly-alpha-olefins (PAO) obtained by copolymerization of C10 and 1-dodecene had a satisfactory performance. The conversion ofα-olefins reached 98.10% under the conditions of molar ratio of mixed C10 to 1-dodecene of 3, molar ratio of initiator (isopropyl alcohol) to raw material of 0.010, the reaction temperature of 25℃, the reaction pressure of 0.4 MPa and the reaction time of 2 h. The PAO possessed excellent performance with the kinematic viscosity 6.02 mm2/s at 100℃ , 34.72 mm2/s at 40℃ , the viscosity index 120, and the pour point -48℃ .%以工业副产混合C10和α-烯烃为原料，BF3为催化剂，在1 L高压反应釜中进行聚合，考察了α-烯烃种类及其用量、反应压力、反应温度、反应时间和引发剂种类及其用量等工艺条件对聚合反应的影响。结果表明，混合C10和1-十二烯共聚得到的聚α-烯烃（PAO）性能较好，以异丙醇为引发剂，在引发剂与原料的物质的量之比为0.010，混合C10和1-十二烯烃物质的量之比为3，温度为25℃和压力为0.4 MPa的条件下反应2 h，原料α-烯烃的转化率为98.15%，聚合产品PAO 100℃的黏度为6.05 mm2/s，40℃的黏度为35 mm2/s，黏度指数为120，倾点为-48℃。
