Abstract
1349769 Polymaleic anhydride FMC CORP 1 Nov 1971 50699/71 Heading C3P Poly(maleic anhydride) is prepared by adding a heated feed mixture maintained at a temperature of 38‹ to 50‹ C. and comprising maleic anhydride, a free-radical polymerization initiator and an inert solvent for maleic anhydride in which the polymeric product is insoluble, to a polymerization reaction zone maintained at an elevated temperature and containing a solvent system comprising an inert solvent for maleic anhydride in which the polymeric product is insoluble and 0 to 25% by weight of maleic anhydride based on the weight of the solvent system, the rate at which the feed mixture is added being controlled to keep the amount of maleic anhydride in the solvent system in the range 0 to 25% by weight, precipitating poly(maleic anhydride) in the solvent for maleic anhydride contained in the reaction zone, and recovering and isolating the poly- (maleic anhydride) product. The monomercontaining molten liquor recovered upon isolating the poly(maleic anhydride) may be admixed with additional maleic anhydride and/or inert solvent for maleic anhydride such that upon return of the molten liquor to the polymerization reaction zone as the solvent system, the composition and volume of the solvent system is at substantially the same level as it was at the initiation of the polymerization reaction. In the examples maleic anhydride is polymerized in the presence of mono-chlorobenzene, diacetyl peroxide in dimethyl phthalate, acetic anhydride, boric oxide, hydrogen peroxide, o - dichlorobenzene, carbon tetrachloride, naphthalene, xylene, di-n-propyl ether, toluene, 2,4-dichlorobenzoyl peroxide, lauroyl peroxide, methyl ethyl ketone peroxide, tbutyl peroxypivalate, di-isopropyl percarbonate and benzene.
