中文摘要：

利用转矩流变仪反应挤出制备腰果酚接枝聚丙烯，考查了加工温度和螺杆转速对反应产物接枝率和聚丙烯主链降解的影响。结果表明，当加工温度为180℃、螺杆转速为30r／min时，制得的腰果酚接枝聚丙烯的接枝率最大，为4．37％，此时聚丙烯主链的降解副反应最少，其熔体流动速率为4．44g／10min，在此条件下制得的产物的剪切应力和黏度均达到最大值。

英文摘要：

Cardanol grafted polypropylene （PP-g-cardanol） was prepared by reactive extrusion in a torque rheometer. Effect of processing temperature and screw speed on grafting rate and degradation of PP was studied. The maximum grafting ratio of PP-g-cardanol was 4.37 % when the processing temperature was 180 ℃ and the screw speed was 30 r/rain. At the same time, the degradation of PP was decreased. The melt flow rate was 4.44 g/10 min. The stress and the viscosity of PP-g-cardanol reached the maximum at this condition.
