Title: Polyarylene sulfide sulfone and its production
Inventor: MATSUOKA HIDEO
IPC: C08G75/20
Filed: 1991-12-13
Abstract: PURPOSE:To provide a new polyarylene sulfide sulfone polymer of excellent heat resistance. CONSTITUTION:A polyarylene sulfide sulfone of a melt viscosity of 6.20-6.60, obtained by reacting an aromatic dihalosulfone with phenolphthalein, an alkali metal salt and a source of sulfur. An aromatic dihalosulfone is reacted with phenolphthalein in a molar ratio of 99/1-60/40 in the presence of an alkali metal hydroixde or an alkyl metal salt in an organic amide solvent and/or an organic sulfone solvent to form an oligomer having halogen atoms at both ends. Next at least one source of sulfur selected from among an alkali metal sulfide, an alkali metal hydrosulfide and hydrogen sulfide is added to the reaction system and reacted with the oligomer at 175-235 deg.C for 1-20hr. Thus, a resin having a particularly high glass transition temperature and excellent thermal decomposition resistance can be obtained. This process is industrially advantageous in that a polymer having a high glass transition temperature which can be varied can be obtained.

A molten steel blown in a converter is degassed, regulated into the prescribed composition, and successively cast and hot rolled. After subjected, if necessary, to hot rolled plate annealing, the resultant steel plate is cold rolled once or is cold rolled two or mote times while process annealed between cold rolling stages to a prescribed sheet thickness, followed by final annealing.  By this method, the silicon steel sheet can be obtained.
