【Abstract】 The effect of ultrasonic vibrations of different frequency on the crystalline behavior of polyolefin was studied by means of PLM and DSC The results showed that the effect of ultrasonic wave on the crystal spherulites and size of polyolefin was obvious at given condition Ultrasonic vibration could make the spherulites of polyolefin more fine,and it was a new method to control the morphology and size of crystal更多还原
