    摘要: These prepolymers containing maleimid functions (f) consist in reaction products of at least one maleic anhydride (I), of at least one compound (II) having at least one -NH2 function and at least one other function F: -OH, -NH2, -NH-, -COOH or -COOR or -OCOR (R = C1-C5 alkyl) and at least one chain forming compound (III) by polycondensation and/or polyaddition; (II) having been first reacted with (I) to open the maleic anhydride cycles, with formation of maleamic acid functions (f) which have then been at least partially re-closed by heat to produce N-substituted maleimids by the groups functionalised by F; the chain having been formed by polycondensation and/or polyaddition of the N-substituted maleimid bearing function F of compound(s) (III), of non aromatised products bearing a function F or not formed at the same time as said N-substituted maleimids, and of the maleic anhydride(s) (I) which could have been in excess after being opened by the compound(s) (II); the functionalities and proportions of (II) and (III) having been selected so as to preclude a gelation of the reaction medium. In (f), (I), and (f'), R , R = H, C11-C12 alkyl or halogen.

    摘要: These compositions comprise at least one compound (A) containing double olefinic bonds depleted of electrons and at least one compound (B) containing double olefinic bonds enriched with electrons. The compound(s) (A) are selected among prepolymers comprising maleimid functions (f) consisting in the reaction products of at least one maleic anhydride (I), of at least one compound (II) having at least one -NH2 function and at least one other function F: -OH, -NH2, -NH-, -COOH, or -COOR3 or -OCOR?3 (R3 = C¿1-C5 alkyl) and at least one chain forming compound (III) by polycondensation and/or polyaddition; (II) having been first reacted with (I) to open the maleic anhydride cycles, with formation of maleamic acid functions (f) which have then been at least partially re-closed by heat to produce N-substituted maleimids by groups functionalised by F; the chain having been formed by polycondensation and/or polyaddition of the N-substituted maleimid bearing the function F of compound(s) (III), of non aromatised products bearing a function F or not formed at the same time as said N-substituted maleimids, and of the maleic anhydride(s) (I) which could have been in excess after being. opened by the compound(s) (II); the functionalities and proportions of (II) and (III) having been selected so as to preclude a gelation of the reaction medium. In (a) (f), (I), and (f'), R1, R2 = H, C¿1?-C12 alkyl or halogen.
