Abstract
The coagulating power of cationic surfactants differing in the length of the radicals was evaluated. Decylpyridinium chloride, dodecylpyridinium chloride, cetylpyridinium bromide, cetyltrimethylammonium bromide, and alkylbenzyldimethylammonium chloride were tested. The coagulant consumption corresponds to the consumption of the commercially used cationic polyelectrolyte, polydiallyldimethylammonium chloride. A hypothesis concerning the disturbing effect of surfactants on the aggregative stability of latex systems was put forward. The surfactant actin mechanism based on micellar-globular interaction was suggested.
