摘要
High strength composites prepared by (A) mixing (1) an aqueous slurry of negatively charged, water-insoluble natural or synthetic fiber such as cellulose fiber, (2) a latex having a high density of pH independent cationic charges, such as sulfonium, bound at or near the particle surface, (3) a water-soluble, high molecular weight anionic polymer co-additive, such as a hydrolyzed polyacrylamide and optionally (4) conventional wet and additives; (B) draining water from the resulting aqueous suspension and (C) drying by heating.
