Abstract

Finely divided copolymers of maleic anhydride are produced by polymerizing a mixture of maleic anhydride and a vinyl ether of a C1- 8 alcohol and/or a vinyl ester of a C1- 8 carboxylic acid in an inert organic liquid in which the monomers but not the copolymer are soluble, with a free radical polymerization initiator and in the presence of a polystyrene, a copolymer of styrene (at least 50%) and an acrylic ester, polyvinyl methyl ether or a polyvinyl ester of a saturated C1- 3 carboxylic acid. The organic liquid may be a saturated aliphatic or cycloaliphatic, or aromatic hydrocarbon. The vinyl ether may be vinyl-(cyclohexyl, diisopropyl carbinol, 2-ethylhexyl, -iso- or n-butyl or ethyl ether and the ester may be vinyl acetate (caprylate or propionate). The free radical initiator may be benzoyl peroxide or azodiisobutyro-nitrile. The copolymer may be treated with ammonia gas to form a hemi-amide ammonium salt.
