Influence of Quaternary Ammonium Salts on Cellulose Modificationand b) development of techniques to control distribution of substituents along the cellulose backbone. Homogeneous substitution,i.e., random distribution of substituents among all the anhydroglucose units in the chain,can be accomplished by initial dissolution of the cellulose substrate followed by

Phase Transfer Free Radical Reactions:1 Polymerization of Acrylic Monomersques of PTC have been concerned for the most part with the transfer of anionic reagents between two immiscible phases for subsequent nucleophilic reactions, the concept is believed to be much more general.. Recently, for instance, a few examples describing extension of the process to cationic (elect
