摘要： Substantially linear, synthetic, water-soluble or water-dispersible cationic interpolymeric surfactants which are particularly useful for reducing the surface tension of an aqueous medium; such surfactants having a critical micelle concentration of from 0.01 to about 10 percent in water at 25.degree. C., a charge density of from about 1 to 5 meq/g and a number average molecular weight of from about 500 to about 40,000 and being composed of a plurality of nonionic hydrophobic units and pH independent hydrophilic cationic units randomly distributed in the backbone of such interpolymeric surfactants and wherein an average molecule of such surfactant contains from 1 to about 5 hydrophilic cationic units substituted with a pendant hydrophobic group, such hydrophobic group being an alkyl or aralkyl group of from about 8 to about 20 carbon atoms are prepared by (1) aqueous, emulsion polymerization of a mixture of ethylenically unsaturated nonionic monomers at least one of which contains an ion-forming group in the presence of a copolymerizable monomeric surfactant to form a latex, (2) reacting the resulting latex with a coreactant to form a water-soluble cationic interpolymer.

摘要： A fibrous product containing (a) a papermaking grade of pulp, (b) a structured particle latex having pH independent cationic groups bound at or near the particle surface and (c) a co-additive. The pulp is represented by unbleached softwood kraft. The latex is represented by a structured-particle latex having (a) a core of a copolymer of styrene and butadiene (b) an encapsulating layer of styrene, butadiene and vinylbenzyl chloride which is reacted with 2-(dimethylamino) ethanol to form quaternary ammonium groups. The co-additive is represented by a hydrolyzed polyacrylamide having a degree of polymerization of 5500. To an aqueous slurry of the pulp are added the latex and an aqueous solution of the co-additive, the resulting suspension is dewatered and dried by heating.
