Maleic acid CAS -No. It is an organic compound and is a dibasic acid which is used in manufacturing fumaric acid, polyesters for fiber lamination, The quantity of maleic acid can be predicted a priori based on single-chain scaling [20].An amorphous linear polymer chain becomes entangled in the network when a chain intersects an arbitrary plane three times, as illustrated in Figure 8.14.The molecular weight of this single chain is defined as M c, or the critical molecular weight of the polymer that is required for entanglements to form. It is utilized for many different substrates as an adhesive promoter like nylon and also metals coated with zinc. The presence of light will convert bromine into bromine radical which will then attach alkene to produce a Bromo-alkane radical due to which a single bond rotation will take place. Fumaric acid is more stable when compared to maleic acid. An organic dicarboxylic acid with a chemical formula of HO2CCH=CHCO2H is called as maleic acid. Maleic acid (MA) is a dicarboxylic acid that undergoes esterification with ethanol in the presence of cation-exchange resin catalysts to form diethyl maleate. In an aqueous solution, these acids get completely dissociated. What to learn next based on college curriculum.
