摘　　要：以聚丙烯(PP)通用料为基础料,通过添加过氧化物制备超高熔融指数(MI)聚丙烯。对PP粉料MI、降温母粒、加工设备及加工工艺等因素对产品MI的影响进行了系统研究。试验结果表明,通过控制PP粉料MI、降温母粒加入量、挤出设备及加工工艺等条件,可稳定生产熔融指数为1300 g/10 min^1500 g/10 min的专用料。High melt index PP special material manufactured by adding peroxide masterbatch,which used general PP as base resin,is introduced.Effect of the PP power MI,peroxide masterbatch,producing equipment and producing conditions on the melt index of products were systematically researched.The test results show that the PP special material with high melt index and stable quality can be obtained through the effective control on the load of chemical degradation agent,the PP powder MI,production equipment and producing conditions.
