高流动高透明无规共聚PP树脂QPT91N的性能研究

摘要

采用Spheripol工艺且选取成核剂M为透明成核剂，生产出高流动高透明的无规共聚 PP树脂 QPT91N。结果表明：QPT91N的力学性能和耐热性能同国内外同类树脂基本相似，而流动性能高于PP1和PP2，雾度则低于PP1和PP2，说明QPT91N的加工性和透明性优于国内外同类产品；QPT91N与PP1的熔融温度和结晶度相当且高于PP2。%High flow high transparent random copolymer polypropylene QPT91N was pro-duced by the Spheripol polymerization process using nucleating agent M as the transparent a-gent.The results showed mechanical properties and heat resistance properties of QPT91N were similar to the same kind of resins of PP1 and PP2 , the flow ability was higher than that of PP1 and PP2 , and haze is better than that of PP1 and PP2 , which indicated processing and transpar-ent properties of the QPT91N overmatched the same kind of products at home and abroad.Melt-ing temperature and crystallinity of the QPT91 N were equal to that of PP1 and higher than that of PP2 .
