AVAILABLE IN QUANTITY T w o carboxyl groups, a conjugated double bond and an active methylene group make Pfizer Itaconic Acid a reactive and versatile molecule. It esterifies readily in high yields. Esters of low-molecular weight alcohols can be polymerized and f a t t y alcohol esters serve as useful plasticizers. Polyhydric alcohol esters form thermosetting resins. Monoesters can also be prepared. The double bond of the acid and its esters is highly reactive : addition polymers are possible with acrylonitrile, methyl methacrylate, vinyl chloride, vinylidene chloride, styrene and butadiene. Hydrogen halides add readily to the double bond, yielding 3-carboxy-4-halobutyric acids. Hydrogen sulfide reacts w i t h two equivalents of diester to form thiotetracarboxylic esters. Cyclopentadiene, vinyl naphthalene and m a n y other dienes undergo Diels-Alder reactions with itaconic anhydride.
