摘　　要：利用正交设计方法对透明聚丙烯(PP)的配方进行试验设计,研究了山梨醇类成核剂A、有机磷酸盐类成核剂B、无机类成核剂C和聚乙烯(PE)4种组分对PP雾度的影响。结果表明,成核剂B和成核剂A对PP雾度的影响最明显,而且4种组分对PP透明性的改善具有协同作用。当成核剂A的含量为0.3%,成核剂B的含量为0.4%,成核剂C的含量为0.15%,PE的含量为5%时,PP的雾度最低,为32.5%。The formula for transparent polypropylene was studied by orthogonal designing method. Effects of a sorbital as the nucleating agent A, a organic phosphate as the nucleating agent B, a inorganic as the nucleating agent C and low density polyethylene on the haze of PP were analyzed respectively. The results showed the effect of nucleating agent B and nucleating agent BA on the haze of PP were most obvious. The four nucleating agents might cause synergistic effect. The best formula were as follows： the content of the nucleating agent A was 0. 3%, the content of the nucleating agent B was 0. 4%, the content of the nucleating agent C was 0. 15% and the content of PE was 5%. The high transparent PP can be achieved with haze of 32.5%.
