本文报道了一种利用绿色、低成本催化剂合成柠檬烯-蒎烯共聚物的简单方法。以H+交换的菱镁矿为催化剂（蒙脱石型粘土），通过阳离子共聚合合成了共聚物.考察了反应动力学、温度、催化剂用量、单体投料比等因素对共聚反应的影响。在溶液中进行共聚，在-5 ℃下反应6 h，产率为40.5%。所得共聚物的结构经红外光谱、核磁共振氢谱和差示扫描量热法证实。最后，为了尊重绿色化学的原则，开发了一种在短反应时间内制备聚（柠檬烯-co-
In this paper, we report a simple method for preparation of poly(limonene-co--pinene) using green and low cost catalyst. Copolymers were synthesized by cationic copolymerization by using H+ exchanged Maghnite as a catalyst (Montmorillonite type clay). Several parameters affecting the copolymerization were investigated such as the reaction kinetics, effect of temperature, catalyst mass and effect of monomer feed ratio. The copolymerization in solution leads to the yield 40.5% at -5 degrees C for a reaction time of 6 h. The structure of the obtained copolymer is confirmed by IR and H-1 NMR spectroscopy, and differential scanning calorimetry. Finally, a new method for the preparation of poly(limonene-co--pinene) in short reaction time was developed, in order to respect the principles of a green chemistry.
