TL;DR: In this article, the authors propose to add to the PULP an ORGANIC ANIONC or NONIONIC AGENT and a CATIONIC RETENTION AGENT while regulating the amount of the Cationic Substance in SUCH a way that the Z-potential of the pULP APPROACHES zero.
Abstract: HIGHLY ABSORBENT CELLULOSE IS PRODUCED BY ADDING TO THE PULP AN ORGANIC ANIONC OR NONIONIC AGENT AND A CATIONIC RETENTION AGENT WHILE REGULATING THE AMOUNT OF THE CATIONIC SUBSTANCE IN SUCH A WAY THAT THE Z-POTENTIAL OF THE PULP APPROACHES ZERO.

TL;DR: The transfer of retention aid (high-molecular-weight cationic polyacrylamide) from pulp fibers to fine and fillers modelled by polystyrene latex (PSL) particles was investigated in the laboratory under simulated papermaking conditions as mentioned in this paper.
Abstract: The transfer of retention aid (high-molecular-weight cationic polyacrylamide) from pulp fibers to fines and fillers modelled by polystyrene latex (PSL) particles was investigated in the laboratory under simulated papermaking conditions. Cleavage of polymer chains during transfer was also investigated.

TL;DR: In this article, the incorporation of cellulose fibers with sucrose has been shown to increase the strength of the produced paper nanocomposites, and the nanoadditive sucrose was proven to act as a retention aid for inorganic fillers such as kaolin.

TL;DR: A series of amphoteric polyacrylamides with different molecular weights and charges were prepared by the copolymerization of acrylamide with sodium acrylate and a subsequent Mannich reaction as discussed by the authors.
Abstract: A series of amphoteric polyacrylamides with different molecular weights and charges were prepared by the copolymerization of acrylamide with sodium acrylate and a subsequent Mannich reaction. The copolymerization was carried out with a redox initiation system via inverse emulsion polymerization. Reaction conditions, factors affecting emulsion stability, and applications as retention aids in papermaking were studied. Experiments showed that an ideal retention aid and a stable latex with wheat-straw pulp of a shorter fiber length could be obtained under the following conditions: the acrylamide/formaldehyde/dimethylamine ratio was 1/1/1.2, a medium of aldehyde and amine was prepared first and then was dropped into an inverse emulsion of anionic polyacrylamide, the reaction temperature was 45°C, the reaction time was 4 h, and the pH was 5.0. When the anionic degree was 5%, the cationic degree was greater than 20%, the molecular weight was between 2 and 3 million, and the filler retention was higher. © 2002 Wiley Periodicals, Inc.

TL;DR: A process for the production of paper and paper-like products which comprises the step of incorporating in the pulp a retention agent comprising a polyalkylene oxide of molecular weight in excess of 1 million and a phenol- or naphthol-formaldehyde or -sulphur resin is described in this article.
Abstract: DISCLOSED is a process for the production of paper and paper-like products which comprises the step of incorporating in the pulp a retention agent comprising a polyalkylene oxide of molecular weight in excess of 1 million and a phenol- or naphthol-formaldehyde or -sulphur resin.
