摘　　要：对双向拉伸膜用PA6切片质量控制指标及其分析方法进行了探讨,提出了双向拉伸膜用PA6切片的试用性企业标准。简述了PA6质量控制项目的分析方法。PA6质量控制项目有水分、单体、低聚物、相对分子质量分布、可萃取物、相对粘度、凝胶粒子、灰分、氧化度、熔点、热焓、结晶度、堆积密度等。The quality control index and analysis method for PA6 chip for biaxial oriented film were discussed. A tentative enterprise standard was proposed for PA6 chip for biaxial oriented film. The analysis method of PA6 quality control index was described. The quality control indexes of PA6 included water content, monomer, oligomer, relative molecular mass distribution, extractable material, relative viscosity, gel particles, ash content, oxidation extent, mehing point, enthalpy, crystallinity, bulk density.
