The condensation is preferably carried out in the presence of a hydrogen halide or at least one compound capable of producing a hydrogen halide. The catalyst is preferably also a Lewis acid or a compound which can be converted into its halide by a hydrogen halide. Examples of the latter are Fe 2 O 3 , ZnO and ZnCO 3 . The N-hydroxy-alkylimide is preferably formed in situ from the corresponding unsubstituted imide. In the examples styrene/divinyl benzene copolymers, a p-vinyl toluene/divinyl benzene copolymer and a styrene/trivinyl benzene copolymer, are condensed with N- hydroxymethyl phthalimie using various Friedel Crafts catalysts.,下面是JPS48102189A -专利的具体信息内容。
