在尼龙(PA)6的熔融挤出过程中引入超声振动外场，通过X射线衍射、高压毛细管流变性能、熔体流动速率测定、特性黏度测定和力学性能测试等手段研究超声振动对PA6性能的影响。结果表明，引入超声外场后，PA6的结晶度提高，热力学稳定的α晶型所占比例提高；特性黏度和粘均分子量降低，熔体黏度降低；力学性能基本保持不变。

The ultrasonic wave was introduced into the melt extrusion of polyamide(PA) 6. By means of XRD,rheometer, melt flow rate,inherent viscosity and mechanical property test,the effects of ultrasonic oscillations on properties of PA6 were studied. The results show that ultrasonic vibration improves both the crystallinity and the proportion ofα-phase crystals of PA6. The inherent viscosity,viscosity average molecular weight and melt viscosity reduce.Moreover,ultrsonic wave has little impact on mechanical properties.
