Styrene maleic anhydride

Styrene maleic anhydride (SMA or SMAnh) is a synthetic polymer that is built-up of styrene and maleic anhydride monomers The monomers can be almost perfectly alternating making it an alternating copolymer [citation needed] but (random) copolymerisation with less than 50% maleic anhydride content is also possible The polymer is formed by a radical polymerization using an organic peroxide

Maleic acid

Maleic acid is converted into maleic anhydride by dehydration to malic acid by hydration and to succinic acid by hydrogenation It reacts with thionyl chloride or phosphorus pentachloride to give the maleic acid chloride (it is not possible to isolate the mono acid chloride) Maleic acid is a reactant in many Diels-Alder reactions

Process for the production of 1:4 butanediol from maleic

Abstract A process has been developed for the production of 1:4 butanediol (1:4 BDO from maleic anhydride (MA) The three process steps are:- a) Esterifiction of MA to produce a dialkyl maleate ester based on a modification of commercially proven esterification technology b) Hydrogenation of the ester at moderate temperatures and pressures to 1:4 BD using novel low pressure ester
