Polymaleic acid, its preparation and its use - Google Patents
A process for the preparation of polymaleic acid by polymerizing maleic anhydride in an aromatic hydrocarbon at from 60° to 200° C., using from 1 to 20% by weight, based on maleic anhydride, of...
Physical and chemical characteristics of poly (maleic acid), a ...
1996年2月20日 · In this paper, we studied a relatively homogenous and easily synthe- sized polymer, polymaleic acid (PMA) to deter- mine its suitability as a model compound for humic substances. Several investigators have shown that both similarities and differences exist between the structural and physical characteristics of PMA and those of soil fulvic acids ...

Poly(maleic acid) – A novel dispersant for aqueous alumina slurry
2013年6月1日 · Poly(maleic acid) (PMA) was investigated as an anionic long chain dispersant for the preparation of highly loaded aqueous alumina slurry. Suspensions with 1 wt% alumina powder were prepared through variation of PMA concentrations at pH 9 to assess its dispersion efficacy in aqueous medium.
Evaluation of maleic acid based polymers as scale inhibitors and ...
2014年2月17日 · Acrylic acid (AA) and maleic acid (MA) polymers were found to inhibit the precipitation of calcium carbonate and gypsum from supersaturated solutions to extents exceeding 90% at concentrations as low as 2 ppm. The molecular weight (MW) was an important parameter in determining the activity of the tested inhibitors.
