  • Carboxylate polymers and processes for their preparation and use
    Patent number: 4808668
    Abstract: Novel cationic, water-soluble carboxylate polymers are provided, which have a high degree of esterification. A process for 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 nitrate. Processes are provided for making such quaternary salts and for use of the novel polymers for separation of water from solids, such as water from sludges.
