Maleic anhydride–benzene and maleic anhydride–acetone molecular complexes

J. Chem. Soc., Chem. Commun., 1978
Concentration- and temperature-dependent n.m.r. chemical shifts, and concentration-dependent heats of dilution and solution, for maleic anhydride in acetone or benzene, are interpreted in terms of equilibria between monomers and solvent–solute molecular complexes, and these complexes are presumed to be involved in photocycloaddition reactions.

Synthesis and Biocompatibility of Maleic Anhydride Copolymers: 1. Maleic Anhydride-Vinyl Acetate, Maleic Anhydride-Methyl Methacrylate and Maleic Anhydride-Styrene

Polymer International, 1997
A series of maleic anhydride (MA)-vinyl acetate (VA), MA-methyl methacrylate (MM) and MA-styrene (S) copolymers were prepared and characterized. By employing various amounts of initiator, MA-VA, MA-MM and MA-S copolymers with molecular weights ranging between 18000 and 219000 were obtained.

Biological activity of maleic anhydride copolymers. I. Biocompatibility and antitumoural effects of maleic anhydride - vinyl acetate, maleic anhydride - methyl methacrylate and maleic anhydride- styrene copolymers

Journal of Biomaterials Science, Polymer Edition, 1997
A series of maleic anhydride (MA)-vinyl acetate (VA), MA-methyl methacrylate (MM), and MA-styrene (S) copolymers were prepared and characterized. On employing various amounts of initiator, maleic anhydride-vinyl acetate, methyl methacrylate, and styrene copolymers with molecular weights ranging between 18,000 and 200,000 have been obtained. The in vivo

Poly(maleic Anhydride)

Journal of Macromolecular Science, Part C: Polymer Reviews, 1975
Abstract The concept that maleic anhydride cannot be homopolymerized is so widely accepted that it is cited in most textbooks on polymer science as an illustration of the steric hindrance imposed by 1,2-disubstitution of the double bond. However, in recent years it has been demonstrated that maleic anhydride readily undergoes polymerization under gamma

Homopolymerization of maleic anhydride

Die Makromolekulare Chemie, 1977
AbstractPyridine and picoline initiated polymerizations of maleic anhydride were investigated in acetic anhydride. It was found that the electrical conductivity of the polymerizing mixture increases in the course of the reaction, and that the initial rate of polymerization increases with increasing monomer and pyridine concentrations, and its values ...

Production of Maleic Anhydride

1982
The first commercial process for MA production was put into use by National Aniline and Chemical in 1928.* It used the Weiss and Downs process employing benzene as a raw material.(1) In 1930, Monsanto made available MA which was a by-product of their phthalic anhydride manufacture. Petrotex also used their butene-based process in the early 1960s, which

Reactions Involving Maleic Anhydride

2016
The rich chemistry that maleic anhydride can participate in makes it the quintessential building block for a variety of small and polymeric molecules that are in use today. This is derived from the electron-deficient conjugated double bond and the cyclic anhydride functionality present.
