Para-phenylene Injection Molding
Poly(para-phenylene), a self-reinforced rigid-chain polymer, has superb mechanical properties but extremely high viscosity. However it can be injection molded with a rapidly heated mold. At a mold temperature of 350°C, complete fill of a 4 mm thick and 50 mm long cavity was achieved. Poly(para-phenylene) may be practically injection molded at a high injection speed with a rapidly heating mold at a mold temperature well above the polymer's glass transition temperature.
