    • A process for producing an isobutene copolymer derivative by: (I) free-radically copolymerizing (a) 10-90 mol % of a monoethylenically unsaturated C4- to C12-dicarboxylic acid, anhydride, or ester, (b) 10-90 mol % of a high-reactivity isobutene polymer having Mn=110-250000 and obtained by polymerizing isobutene in the presence of an iron-halide-, aluminum trihalide-, or alkylaluminum halide-donor complex, each donor being an ether or carboxylic ester function, or in the presence of a Lewis acid complex containing an organic sulfonic acid, and (c) 0-50 mol % of a monoethylenically unsaturated compound copolymerizable with (a) and (b), to obtain an intermediate isobutene copolymer; and (II) reacting the carboxylic acid functions in the intermediate with at least one of ammonia, an amine, and an alcohol, to form a moiety containing at least one of a hydroxyl, carboxylic ester, amino, quaternized amino, amido, and imido group.
    • 异丁烯共聚物衍生物的制备方法:(I)10-90摩尔%的单烯属不饱和C4-至C12-二羧酸,酸酐或酯的自由基共聚合,(b)10-90摩尔% 的Mn = 110-250000的高反应异丁烯聚合物,并且通过在卤化铁,三卤化铝或卤化烷基铝卤化物供体络合物的存在下聚合异丁烯获得,每个供体是醚或羧酸酯官能团,或 在含有有机磺酸的路易斯酸络合物的存在下,和(c)0-50mol%可与(a)和(b)共聚的单烯键式不饱和化合物,得到中间体异丁烯共聚物; 和(II)使中间体中的羧酸官能团与氨,胺和醇中的至少一种反应,以形成含有羟基,羧酸酯,氨基,季铵化氨基,酰胺基和亚氨基中的至少一个的部分 组。
