FINE GRANULATED,SINTERABLE POLYVINYLCHLORIDE MOULDING MATERIAL,AND PROCESS FOR PRODUCING THEM

摘要

Powdery molding compositions capable of being sintered made from polyvinyl chloride, which are especially suitable for the manufacture of separator plates for electric cells, and which substantially consist of a suspension polyvinyl chloride, from 0.003 to 0.45 weight %, relative to the molding composition, of free sulfonic acids selected from the group of alkylarylsulfonic acids and/or alkylsulfonic acids, and 1/9 to 7/3 of said 0.003 to 0.45 weight % of anions of said sulfonic acids, in the form of their salts with organic cations, selected from the group of quaternary ammonium cations.
