Using an AlCl₃/SbCl₃binary catalyst,a mixture of α-pinene and β-pinene was polymerized to produce,a copolymer 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 SbCl₃all 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 copolymer was also characterized by solubility,GPC,ozonization,UV,IR and¹³C NMR.
