Synthesis and application of amphoteric polyacrylamide
The synthetic method of amphoteric polyacrylamide is studied. The effects of reaction temperature, reaction concentration and reaction time are discussed in details. In the flocculation tests , the flocculant behaviors of inorganic polymer coagulant and the composites of inorganic polymer coagulant and organic polymer coagulant are studied respectively.
Carboxymethyl cellulose (CMC) is the most widely used co-binder and rheology modifier in paper coating. This work presents an investigation on the effects of CMC on coating structure development by measuring viscosity of the coating colors and by characterizing properties of the dried coatings. The results showed that CMC addition increased coating color viscosity and impeded latex migration

Glyoxalation of vinylamide polymer - Wright, Matthew D.
A glyoxalated vinylamide polymer formed by the process of the invention (example 1) and a conventionally glyoxalted vinylamide polymer (example 2 comparison) are separately added to the furnish in the thin stock before the fan pump. The glyoxalated adduct samples are applied at 1 lb/ton and 3 lb/ton for each (based on dry weight of furnish).
Application of the adduct to wet paper or board may be accomplished by any conventional means. Examples include but are not limited to size press, padding, spraying, immersing, printing or curtain coating. The polymers of the invention are absorbed by the paper-making fibers at pH values ranging from about 3.5 to about 8.

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present
