FREMGANGSMAATE TIL FREMSTILLING AV EN SINTERBAR, FINDELT FORMMASSE AV POLYVINYLKLORID OG ANVENDELSE AV EN SLIK FORMMASSE.

摘要

The invention provides a process for the production of sinterable, finely divided molding compounds based on polyvinyl chloride by suspension polymerization of vinyl chloride in the presence of a suspending agent mixture of sulfated carbohydrate ester and cellulose ether. The compounds are useful for the production of sintered molded articles, such as separator plates. The molded articles or plates exhibit a slight electrical resistance and a high porosity with good acid storage volume.
