More Information
Summary:Disclosed are a styrene polymer molding material which has a high degree of syndiotacticity, a weight average molecular weight of 50,000 or more, and at least one melting points of 285 DEG C or higher, and a process for producing the same by melting a styrene polymer having a high degree of syndiotacticity and then molding it under a stress of 1 x 10 dyne/cm or higher. The styrene polymer molding material of the present invention has excellent heat resistance. In addition, according to the process of the present invention, the above polymer molding material having excellent heat resistance can be prepared by a simple operation, and thus has marked advantages for practical use.
