[Effect of crystallization and branch on fine structure of orthorhombic in polyethylene].
The CH2 rocking bands are used as a probe to monitor the crystalline behavior of polyethylene segments in a series of poly (ethylene-octene) copolymers. High resolution and cryogenic FTIR spectra reveal that different composition and/or crystalline condition of the copolymers result in significant variation on the CH2 rocking bands including the change in peak position, band width and A730/A720. We conclude that side chain in the copolymer can influence the structure of the orthorhombic polyethylene crystallite although they can not enter the crystal lattice.
