摘要
采用毛管流变仪分析均聚聚丙烯(PPH)、助剂偏氟乙烯和六氟丙烯共聚物[P(VdF-HFP)]、高密度聚乙烯(HDPE)对共聚聚丙烯(PPB)黏度变化的影响。结果表明:PPB中加入PPH、P(VdF-HFP)、HDPE可以减轻挤出时发生畸变,同时PPB的物理性能并无明显变化。
The effects of homo-polypropylene(PPH),vinylidenefluoride-hexafluoropropylene copolymer[P(VdF-HFP)]and high density polyethylene(HDPE)on the viscosity of block co-polypropylene(PPB)were analyzed by capillary rheometer.The results show that the distortion of PPB can be reduced by adding PPH,P(VdF-HFP)and HDPE,and the physical properties of PPB have no obvious change.
