Description
Polymaleic acid is the homopolymer of maleic acid. It is very stable in presence of chlorine and other oxidizing biocides. It has good scale inhibition and high temperature resistance properties. Therefore, it can be used in the water desalination plants. It is also an excellent calcium carbonate antiscalant upon high temperature and in the high alkaline cooling water systems. In addition, it can be used in combination with zinc salts as a corrosion inhibitor. It can also be used as concrete additive and for crude oil evaporation. It can be manufactured through the polymerization of maleic anhydride I an aromatic hydrocarbon upon 60° to 200° C.

Biological Activity
PMA (polymethacrylate) forms nanodiscs spontaneously by fragmentation or solubilization of the lipid bilayers. It is used in designing of nanodisc-forming polymer to mimic the amphiphilic nature of proteins and peptides. PMA N-C4-60-4.7 efficiently solubilised the lipid membrane and forms lipid nanodiscs with 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC). The addition of PMA N-C4-60-4.7 lowered the light scattering intensity of Escherichia coli suspension.
Safety Profile
When heated to
decomposition it emits acrid smoke and
irritating fumes.
