Abstract

Poly(1-oxotrimethylene) (POTE) was prepared by polymerization of ethylene and carbon monoxide gases in an autoclave using a palladium catalyst system. POTE fibers having different draw ratios were prepared and characterized using differential scanning calorimetry (DSC), X-ray diffraction, and a universal testing machine (UTM). Tensile strength and modulus of POTE fibers having a draw ratio of 16 obtained by drying at 220 °C were found to be 13.4 and 369.8 g/denier, respectively. These values are much larger than those of poly(ethylene terephthalate) (PET) and Nylon 6 fibers that are currently used as tire cords.
