Study on the preparation of a novel amphoteric
According to the papermaking system's latest developing trend,designed and prepared a novel amphoteric polyacrylamide paper dry-strength agent,which is the copolymerization product of AM,DMC and MA,and had been modified and with branched structure. Its optimum preparing conditions were determined as follows:the molar ratio of AM,DMC and MA is 100:6:3,the total solid content of the product is

dry strength resin & additive – anionic & cationic
Our superior Dry Strength Resin, known as OPL DSR, is a highly sought after paper chemical that adds dry strength to paper. OPL DSR is available in three forms: anionic, cationic and amphoteric. The main function of Dry Strength Resins is to increase strength per unit of bonded area between fibers in any sheet of paper.
Papermaking Auxiliaries: Anionic polyacrylamide can be used as a clarification, retention aid, filter aid and paper dry and wet strength enhancer for caustic soda. Anionic polyacrylamide is used as a clarifying agent for sugar juice in the sugar industry. Anionic polyacrylamide is used as an additive and binder in aquatic feed. About RUNNENG
Polyacrylamide Applications in Papermaking Industry
From the movement of the waterline in the net, it increases the dehydration speed, thereby, it improves the working speed and the dry degree of the paper leaving the net, which saves the steam. With more adding of the anionic polyacrylamide, there is only a little influence to the paper strength, but the paper evenness gradually gets worse. 2.
Full Article. Synthesis and Application of a Cationic Polyacrylamide Dry Strength Agent with Anionic Content. Guangyan Wang and Yi Jing* A new net-cationic polyacrylamide dry strength agent was synthesized through free radical polymerization using acrylamide (AM), itaconic acid (IA), N,N-dimethylacrylamide (F), and sodium methallyl sulfonate (T).
US Patent for Modified of improving dry strength and/or
Modified of improving dry strength and/or drainage of a paper or paperboard Mar 2, 2017 - Solenis Technologies, L.P. A method of improving dry strength and/or drainage of a paper or paperboard by adding to a paper or paperboard furnish, a graft copolymer composition of a vinyl monomer and a functionalized vinylamine-containing base polymer
Applied in papermaking, carrageenan can obviously improve paper strength by strengthening the bonding between cellulose fibres, which was confirmed through FTIR spectra and SEM images. As an anionic dry strength agent, carrageenan decreased the efficiency of some cationic retention aids such as CPAM, thus reducing filler retention.
