Abstract

Abstract

High density polyethylene was crystallized at static high pressure from 1 GPa to 2 GPa. The Young's modulus of the sample treated by high-pressure compression was measured with the compression method. The results show that the Young's modulus is increased both with the pressure and the crystallinity, and its maximum value is 1.46 GPa. The formation of the extended-chain crystal is an important factor for the increase of Young's modulus.
