采用滴定法对进口聚乙烯,聚丙烯和聚苯乙烯原料中过氧化值的情况进行了普查。分别抽查9个牌号的聚乙烯原料、14个牌号的聚丙烯和10个牌号的聚苯乙烯塑料,结果表明聚乙烯和聚丙烯树脂中过氧化值较小而且分布均匀,而聚苯乙烯树脂的过氧化值较大并且与生产工艺有关。

The peroxide value of imported polyethylene,polypropylene and polystyrene resin were determined by titration method.9 grades of imported polyethylene resin,14 grades of imported polypropylene resin and 10 grades of imported polystyrene resin were conducted a spot check.The results showed that the peroxide value of polyethylene and polypropylene resin were small and evenly distributed,and the polystyrene resin was large related with production technology.
