摘　　要：发现预氧化聚丙烯/抗静电剂/聚丙烯三元共混料的表面电阻率的下限值可达106,可以作为母料进一步与普通聚丙烯共混,用于做防静电薄膜。随着抗静电剂含量的增加、热氧处理温度的升高和热氧处理时间的延长,三元聚丙烯共混母料的表面电阻率显著下降。普通聚丙烯的加入具有一定的稀释效应,会在一定程度上影响三元聚丙烯共混母料表面电阻率的进一步降低。It has been found that the lower limit value of the pre-oxidized PP/antistatic agent/polypropylene ternary blends could fall down to 106 Ω, using as the masterbatch which could be further blended with ordinary polypropylene to manufacture antistatic PP film. The surface resistivity of the ternary blending PP masterbatch significantly decreased with the increase of the adding level of the antistatic agent, the raise of thermooxidizing treating temperature and the increase of thermooxidizing treating time. Diluting Effect took place in some cases where ordinary polypropylene was added in the ternary blending system to cause definite reduction of the surface resistivity of the ternary blending PP masterbatch.
