Abstract

1,195,737. Papermaking. NALCO CHEMICAL CO. 6 Oct., 1967 [25 Jan., 1967], No. 45944/67. Heading D2A. The freeness of a slurry of cellulosic fibres is improved by the addition of a copolymer of acrylanide or methacrylamide with a dialkylamino-alkyl acrylate or alkacrylate in which the alkyl groups contain 1, 2, or 3 carbon atoms.
