The chemical property of fumaric acid is similar to that of maleic acid.
Usage:
Fumaric acid is used to produce unsaturated polyester resins.
Such resins are characterized by good chemical resistance
properties and heat resistance. The copolymer of fumaric acid and
vinyl acetate is a good adhesive, and the copolymer of fumaric
acid and styrene is the raw material of the manufacture of glass
fiber reinforced plastic. The plasticizer made by fumaric acid is
nontoxic, and it can be used as a vinyl acetate emulsion
contacted with food. The product is used as a fine chemical
intermediates for pharmaceutical and optical bleaching
agent.
