Description:Dimethyl maleate is an organic compound with the formula C6H8O4. It is the (Z)-isomer of the dimethyl ester of fumaric acid.Dimethyl maleate is used in many organic syntheses as a dienophile for diene synthesis. It is used as an additive and intermediate for plastics, pigments, pharmaceuticals, and agricultural products. It is also an intermediate for the production of paints, adhesives, and copolymers.
Dimethyl maleate has also found use in applications where improvements in the hardness and toughness of polymer films are desired. This includes, in particular, the improvement of anti-blocking properties of copolymers of vinyl acetate with DMM. It is also used as an internal modifier to increase the glass transition temperature of styrene or vinyl chloride polymers.
