    摘要: A metallic press die having an edge portion or high pressure portion for processing a workpiece therewith is made by overlaying a welding material to that portion of a base material for the metallic press die which forms the edge portion or high pressure portion, and then machining an overlaid portion into a predetermined shape of the edge portion or high pressure portion. The welding material has a hardness after welding of HRC 45 or below. After the machining step, the overlaid portion is subjected to a subzero treatment to increase the hardness of the overlaid portion. The welding material contains, as a basic composition thereof, 0.5-1.5% by weight of carbon (C), 0.2 -2.0% by weight of silicon (Si), 0.3-6.0% by weight of manganese (Mn), 0.3-10.0% by weight of chromium (Cr), 0.3-10.0% by weight of cobalt (Co), and the remaining parts of iron (Fe) inclusive of unavoidable impurities, and wherein a starting temperature of martensitic transformation is 150 .degree. C. or below.

    摘要: There are disclosed a catalyst well suited for producing a styrenic polymer having a high degree of syndiotactic configuration which comprises a transition-metal compound such as pentamethylcyclopentadienyltrimethyltitanium and a coordination complex compound comprising an anion in which a plurality of radicals are bonded to a metal and a quaternary ammonium salt, the compound being exemplified by orthocyano-N-methylpyridinium tetra(pentafluorophenyl)borate, or comprises an alkylating agent such as triisobutylaluminum in addition to the above two compounds; and a process for producing a styrenic polymer having a high degree of syndiotactic configuration by polymerizing a styrenic monomer using the aforementioned catalyst. Consequently, a styrenic polymer having a high degree of syndiotactic configuration can be produced effectively without the use of an expensive aluminoxane required in a large amount if used.
