| Abstract: |
| The influencing factors on the polymerization of α-pinene with catalysts of AlCl3/SbCl3 were investigated.A polyterpene resin which has softening point at 138℃(ring and ball) and colour of Gardner 3(Fe-Co) was obtained in the following conditions.The reaction temperature was-15℃,the mass ratio of AlCl3/α-pinene and AlCl3/SbCl3 were 2.0%,2 respectively,the concentration of α-pinene was 50%,the dropping speed of α-pinene was 120 drops/min,the reaction time was 4 h and the catalysts were added in stepwise mode.The yield was over 80%. |
