摘　　要：研究了在气相聚丙烯工艺装置用NA-Ⅱ催化剂和进口催化剂生产的双向拉伸聚丙烯(BOPP)专用树脂性能,并与高速BOPP树脂F280S进行了比较。结果表明,NA-Ⅱ催化剂生产的BOPP专用树脂物理性能符合优级品标准,雾度及弯曲模量好于进口催化剂生产的BOPP专用树脂;相对分子质量及其分布与进口催化剂生产的BOPP专用树脂相当,与F280S有明显区别。The authors studied performances of the speciality resins for biaxially oriented polypropylene （BOPP） produced in a gas phase polypropylene plant with NA-Ⅱ catalyst and imported catalyst respectively, and further compared the speciality resin with high speed BOPP resin F280S. The results confirm that the BOPP resin synthesized with NA-Ⅱ catalyst has the physical properties conformed to the requirements of the top grade product and is superior to its counterparts prepared with the imported catalyst in haze value and flexural modulus. The relative molecular mass and its distribution of the speciality resin are equivalent to those of its counterpart prepared with imported catalyst but obviously different from those of F280S.
