| Abstract: | The degree of crystallinity,crystallite size,cell parameters,heat of fusion,and totalmethyl groups in the side chain of both of standard and ultra-high molecular weight HDPEwere determined by WAXD,DSC,and IR method.The changes of these characteristic values with the molecular weight and the effects ofcrystal size and cell parameters on the melting point of polymer were studied.The differences in crystallinity between the HDPE after crystallized from the melt by cooling andthose obtained directly from the reactor were also studied and discussed. |
