quaternary ammonium salts

Technological and ecological aspects of the practical application of quaternary ammonium salts in production of synthetic emulsion rubbers in Russia

In the review physical and chemical aspects and technological parameters of the rubbers production processes from industrial latex with application of ammonium halogenides, tetraalkylammonium salts, poly-(N,N-dimethyl-2-oxypropyleneammonium) chloride, poly-N,N-dimethyl-N,N-diallylammonium chloride, and his copolymer with SO2 are considered. A significant ecological effect of polymeric flocculants application is shown. 

Chemical Modification of Dianic Epoxy Resin by Fluorine-Containing Alcohols

New epoxy resins with fluorine atoms have been synthesized via chemical modification of dianic epoxy resin with fluorine-containing alhocols-telomers C7, C9 and C13, using benzyltriethylammonium chloride and KOH as a catalyst system. Their characteristics have been examined. The structure of synthesized products has been confirmed by IR-spectroscopy. It has been shown that new epoxy resins may be used as active plasticizers for industrial epoxy resin.
