摘要
以复合的AlCl3/SbCl3为催化体系,通过改进的工艺参数调控α-蒎烯与β-蒎烯的聚合反应活性,在反应温度0℃,m(α-蒎烯):m(β-蒎烯)=5:5,α-蒎烯、β-蒎烯、SbCl3滴加速度均为4.0mL/min,ω(AlCl3/蒎烯)=3.0%,AlCl3颗粒直径为0.17~0.61mm,m(SbCl3)/m(AlCl3)=0.5,保温时间4.0h,合成了色泽(铁钴)为3,得率为85.7%,软化点(环球法)为136.0℃的共聚物。并用溶解性、凝胶渗透色谱(GPC)、臭氧化、紫外光谱(UV)、红外光谱(IR)、核磁共振光谱(13^C NMR)等测试技术对共聚物结构进行了分析和表征。
Using an AlCl3/SbCl3 binary catalyst, a mixture of α-pinene and β-pinene was polymefized to produce, a eopolymer of α-pinene and β-pinene with a softening point of 136.0 ℃ and a color grade of 3 (Fe-Co) with a yield of more than 85.7% under the following conditions:polymerization temperature 0 ℃ ; m(α-pinene) : m(β-pinene) = 5 : 5 ; addition rates of α-pinene, β-pinene and SbCl3 all being 4. 0 mL/min ; ω ( AlCl3 ) = 3.0% and AlCl3 powder of 0. 17 - 0. 61 mm size ; m ( SbCl3 )/m ( AlCl3 ) = 0. 50 ; holding time 4. 0 h. The eopolymer was also characterized by solubility, GPC, ozonization, UV , IR and 13^C NMR.
