ABSTRACT:
A sinterable, finely divided molding material and the preparation thereof are described. The molding material is composed of a vinyl chloride (graft) copolymer, at least one anionic and/or nonionic emulsifier and, if appropriate, small quantities of additives.
The vinyl chloride (graft) copolymer contains 95 to 70% by weight of polymerized units of vinyl chloride, 5 to 30% by weight of polymerized units of an alkyl acrylate having 3 to 10 carbon atoms, 0 to 7% by weight of polymerized units of ethylene and 0 to 15% by weight of polymerized units of vinyl acetate.
The molding material is suitable for the production of flexible, sintered moldings, in particular separator plates, for electric cells.
