Swelling of organoclays in styrene. Effect on flammability in polystyrene nanocomposites

eXPRESS Polymer Letters, 2010
In this work the effect of the compatibility between organoclays and styrene on the flammability of polystyrene/clay nanocomposites obtained through in situ incorporation was investigated. The reactions were carried out by bulk polymerization.

Sorption of methylene blue from water by organoclays

, 1999
Isotherms were measured for sorption of methylene blue by organoclays. The organoclays were prepared from kaolinite and bentonite by replacing the natural exchangable cations of the quaternary ammonium ions HDTMA (hexadecyltrimethyl ammonium),TMPA ...
