中文摘要:采用3,6,9-三乙基-3,6,9-三甲基-1,4,7-三过氧壬烷(301)对聚丙烯(PP)进行降解处理,通过微量混合流变仪制备高流动性PP。研究301添加量和共混时间对PP的结晶行为、流变性能和热稳定性的影响。结果表明:随着301添加量的增加,PP的熔体流动速率不断增加。随着301添加量的增加,PP的热稳定性先降低后上升,PP的熔融温度降低,结晶温度升高,结晶度下降。随着共混时间的增加,加入过氧化物PP的熔体流动速率不断增加,PP的流动性得到明显提升。随着共混时间的增加,PP的热稳定性下降,PP熔融温度下降,结晶温度上升,结晶度不断下降。
外文摘要:Polypropylene(PP)was degraded by 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxynonane(301),and high fluidity PP was prepared by micro-mixing rheometer.The effects of 301 addition and blending time on the crystallization behavior,rheological properties and thermal stability of PP were studied.The results show that the melt flow rate of PP increases with the increase of 301 addition.With the increase of 301 addition,the thermal stability of PP decreasess first and then increasess,the melting temperature of PP decrease,the crystallization temperature increasess,and the crystallinity decreases.With the increase of blending time,the melt flow rate of PP with peroxide increases continuously,and the fluidity of PP is obviously improved.With the increase of blending time,the thermal stability of PP decreases,the melting temperature of PP decreases,the crystallization temperature increases,and the crystallinity decreases.
