- 摘要：为了满足市场需求，中韩（武汉）石油化工有限公司（简称“中韩石化”）在 STPP 装置开发了透明聚丙烯（PP）。研究了透明成核剂NA1及NA2对无规共聚PP性能的影响。结果表明，加入透明成核剂，无规共聚 PP的透明性能、力学性能、耐热性能及结晶性能均得到改善。当透明成核剂含量在 0.15%~0.2% 时，NA1 对无规共聚 PP 透明性能的改善作用优于 NA2；当透明成核剂含量在 0.25%时，NA2对无规共聚 PP透明性能的改善作用优于 NA1。此外，NA2对无规共聚PP的结晶性能及黄色指数的改善作用均优于NA1。Abstract: In order to meet the market demand, ZHSH(Wuhan) Petrochemical Company developed transparent polypropylene (PP)in the STPP plant. The effect of transparent nucleating agents NA1 and NA2 on random copolymerization of PP was studied. Theresults showed that the transparent properties, mechanical properties, heat resistance and crystallization properties of randomcopolymerized PP were improved by adding transparent nucleating agent. When the content of transparent nucleating agent was0.15% -0.2%, NA1 had better effect on the transparency of random copolymerization PP than that of NA2. When the content oftransparent nucleating agent was 0.25%, NA2 had better effect on the transparency of random copolymerization PP than that of NA1.In addition, NA2 had better effect on the improvementof the crystallization property and yellow index of random copolymerization PPthan NA1.
