<p>Vinyl chloride polymerisation. Addition to DT.1720430.7. The emulsifiers used are alkali metal salts of alpha-sulphoaliphatic acids having 12 to 24 C-atoms, used in amount 0.6 to 4.0 weight-% with respect to monomer(s). Polymn. is effected at pH 7 to 10, and the emulsion is admixed. prior to working-up, with 0.02 to 2.0%, with respect to solids content, of alkaline agent.</p> |
