Preparation of Acrylamide Polymers

Nervous System Degeneration Produced by Acrylamide Monomer

“…Up to 2% residual monomer is considered acceptable for some industrial applications of polyacrylamide, as in the flocculation of ore slimes (14). The Food and Drug Administration has established a maximum level of 0.05%o residual acrylamide monomer for polymers used in paper and paperboard in contact with foodstuffs.…”

“…The present concern with the neurotoxic property of acrylamide monomer is related to the vast and increasing production of the chemical for the manufacture of high molecular polymers which enjoy important applications in industry and commerce (14). There are two areas for concern, both of which arise from the central features of acrylamide neurotoxicity that the effects of acrylamide are related to the accumulated dose and that the nervous system damage develops insidiously (2,4,(15)(16)(17)(18): one is the degree to which people employed to manufacture acrylamide are daily exposed to the neurotoxin, and second, the extent of the exposure of the populace through the deployment in the environment of acrylamide polymers contaminated with small amounts of acrylamide monomer (19).…”

Synthesis of highly methanol selective membranes for separation of methyl tertiary butyl ether (MTBE)–methanol mixtures by pervaporation

“…It has also been found that most uniform copolymer is formed near pH 4 [16]. Thus, the pH of the reaction medium was maintained at around 4 by using aqueous sulfuric acid solution [17]. The comonomer compositions of acrylamide and HEMA were calculated on the basis of their relative reactivity ratios values as given in Table 1 to obtain the three copolymers i.e.…”

“…The pH of the reaction medium is very important since amide group of acrylamide is hydrolyzed at high pH while cross-linking through imidization occurs at low pH and high temperature [17]. It has also been found that most uniform copolymer is formed near pH 4 [16].…”

Characterization of poly(acrylamide-co-acrylates) obtained by inverse microemulsion polymerization

“…The synthesis of high molecular weight watersoluble copolymers is currently the object of numerous studies due to their great practical importance [1,2]. In addition to their many uses like flocculants for numerous subtrates, in coatings and adhesives, they also constitute efficient thickeners in oil recovery processes [3,4].…”
