ABSTRACT NOVEL CARBOXYLATE POLYMERS AND PROCESSES FOR THEIR PREP RATION AND USE Novel cationic, water-soluble carboxylate polymers are provided, which have a high degree of esterifica- tion. A process making the polymers is provided by which selected quaternary salts of epoxy alkyl amine compounds are used for high conversion to ester groups, which salts have a low degradation reactivity toward the epoxy group of the esterification compound. Such a quaternary salt is glycidyl trimethyl ammonium ni- trate. Processes are provided for making such quater- nary salts and for use of the novel polymers for separation of water from solids, such as water from sludges.
