Copolymerization of phenanthrene and maleic anhydride
Journal of Polymer Science Part A-1: Polymer Chemistry, 1968Abstract A study of the copolymerization of phenanthrene and maleic anhydride was carried out at 60°C using AIBN as a radical initiator. The copolymerization is characterized by the fact that these two monomers are hardly homopolymerized, and the complex formed by the two monomers may promote the copolymerization.

Production of Maleic Anhydride
1982The 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

Homopolymerization of maleic anhydride
Die Makromolekulare Chemie, 1977AbstractPyridine 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 ...

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
Journal of Macromolecular Science: Part A - Chemistry, 1976Abstract It is well known that molecular oxygen inhibits the homopolymerization of vinyl-type monomers [1]. During several attempts in this laboratory to homopolymerize vinyl acetate in benzene, no polymer was formed over a period of one week, even though the initiator was varied as to type and concentration.
