| Physical and Chemical Properties | Chemical properties The poly-p-phenylene prepared by the catalytic polymerization of benzene through copper chloride/aluminum chloride is a powder with particularly good heat resistance and is insoluble and insoluble, but it can be oriented by solid-phase extrusion. The poly-p-phenylene powder obtained by polymerization is placed in a metal mold with a pore size of 0.5mm, and is extruded into fibers at a temperature of 260 ℃ and a pressure of 10N/m2. The temperature during extrusion can be adjusted, A small amount of polyethylene can also be added to reduce the temperature and pressure, and a small amount of graphite can also receive the same effect. The prepared fiber has a smooth surface but is very brittle. |
| Use | Applications for conductive fibers. |
ICI synthesis of polyp-phenylene fibers. Compound I is synthesized by microbial oxidation of benzene. Prepolymer (II) is prepared by free radical polymerization with a polymerization degree of 600-1000. Prepolymer (II) soluble in organic solution is made into fiber, then polyp-phenylene fiber (III) is prepared by heating at 140-240 ℃, and then conductive fiber is obtained by doping.
