摘要 |
Disclosed are a material for extrusion molding comprising a styrene-based polymer having a high degree of syndiotactic configuration, a melt viscosity of 10<3> to less than 10<6> poise measured at 300 DEG C and a shearing rate of 10/sec, and a crystallinity of 15% or more, a process for preparation of the said material and a process for preparation of a molding product therefrom. The molding product prepared according to the present invention has excellent properties such as heat resistance and chemical resistance. |
