Deformation of polyethylene oxide, nylon-11 and polyethylene terephthalate by rolling

The tensile properties and structural changes in rolled polymers were studied for several systems, including: polyethylene oxide (PEO), nylon-11 and polyethylene terephthalate (PET). All showed tensile properties typical for rolled systems, i.e. increase in strength along the roll direction, and a corresponding decrease perpendicular to the roll direction. Wide angle X-ray diffraction showed that for PEO and PET the chains were aligned parallel to the roll direction. Molecular chains for nylon-11 are preferentially tilted from 20 to 25° to the roll direction at low deformation. This tilt decreased with increased rolling and the chains were aligned in the roll direction at high deformation. Nylon-11 and PET showed four-point patterns typical of such systems in the small angle X-ray region.
