lithium polyacrylate-polyacrylamide blend as polymer at thailand
Spectrophotometry was used to study the interaction of high-molecular polyacrylamide with cationic dyes: Methylene Blue, Acridine Yellow, and Toluidine Blue. Polyacrylamide samples were modified by alkaline hydrolysis. The optimum conditions of the formation of polyacrylamide–cationic dye adducts and their compositions were found. Simple procedures are proposed for the determination of the
Only Sawant and Morawetz report imidization as a reaction pathway in alkaline hydrolysis of PAm 4. Guerrero, et a1. 10,13, on the other hand, report seeing no intramolecular imide structure using a variety of characterization techniques. Generally speaking, the opinions have been widely divided in the literature on this particular issue.
