Abstract: In the first aspect of the present invention, there is disclosed a method for producing a copolymer of an alkyl vinyl ether and maleic anhydride which comprises removing an organic solvent used in a reaction under a temperature so that a slurry state can be maintained. According to the first aspect, such a copolymer of the alkyl vinyl ether and maleic anhydride which contains a little amount of the solvent remaining therein as disclosed in the second aspect of the present invention, can be obtained. Further, it can be avoided that a specific viscosity of the copolymer of the alkyl vinyl ether and maleic anhydride is lowered, by means of a method for producing a copolymer of alkyl vinyl ether and maleic anhydride which comprises shielding oxygen in a polymerization, as disclosed in the third aspect of the present invention.

Abstract: A molded article is produced from a flame retardant resin composition obtained by compounding a thermoplastic resin or thermosetting resin with a flame retardant composition comprising as essential ingredients a fluorine compound (A) represented by the following formula (1): R1—SO2—R2 or R1—SO3?M+??(1) (wherein R1 represents a C1-C12 perfluoroalkyl group, a C2-C8 perfluoroalkenyl group, a C6-C12 perfluoroaryl group which may be substituted, a C3-C12 perfluoroalicyclic hydrocarbon group, or a C7-C12 perfluoroaralkyl group; R2 represents a halogen atom, an N-alkylamino group, or an N-alkyl-N-hydroxyalkylamino group; and M represents an alkali metal) and a polyester resin (B). The molded article has flame retardancy despite addition of the fluorine compound (A) in a very small amount. Excellent dispersion of the fluorine compound (A) is attained, and bleeding of the compound (A) is prevented.
