  • Prepolymers having maleimide functions the process for preparing them and their uses
    Patent number: 6271339
    Abstract: These prepolymers having maleimide functions (f) consist in the reaction products of at least one maleic anhydride represented by formula (I); of at least one compound (II) having at least one —NH2 function and at least another function F selected from the group consisting of —OH, —NH2, —NH—, —COOH, —COOR3 or —OOCR3; of at least one compound (III) capable of forming the chain of the prepolymers by polycondensation and/or polyaddition, said compound(s) (II) having first reacted with said maleic anhydride(s) (I) in order to open the maleic anhydride rings with formation of maleamic acid functions (f′), said maleamic acid functions having then been at least partially closed again under the action of heat into maleimides N-substituted by groups functionalized by a function F, the chain of said prepolymers having been formed by polycondensation and/or polyaddition of the N-substituted maleimide formed bearing the function F; of compound(s) (III) of uncyclized p
