    摘要： Oriented, syndiotactic, optically transparent vinylaromatic polymers are prepared by a process comprising heating the polymer to a temperature above its crystalline melting point, cooling the polymer to a temperature less than an orientable temperature at a rate sufficient to avoid substantial crystal formation, and inducing strain into the polymer while at a orientable temperature to induce crystal formation and molecular orientation.
