    Abstract: The invention relates to novel alkoxy substituted maleimides of the formula I where R1 is hydrogen, C1-C8-alkyl, C2-C8-alkenyl, phenyl or phenylalkyl, and the organic radicals may furthermore carry inert substituents, and R2 and R3 are each C1-C4-alkyl, C2-C4-alkenyl, C1-C4-haloalkyl or C2-C4-haloalkenyl, and alkoxy-substituted maleic anhydrides of the formula II II where R2 is C1-C4-alkyl, C2-C4-alkenyl, C1-C4-haloalkyl or C2-C4-haloalkenyl and Z is hydrogen, halogen or a radical OR3, where R3 is C1-C4-alkyl, C2-C4-alkenyl, C1-C4-haloalkyl or C2-C4-haloalkenyl. The invention further relates to processes for preparing such maleimides I and the corresponding maleic anhydrides II and their use as graft monomers in graft polymers based on polyphenylene ethers.

    Abstract: Graft polymers comprising A) a polyphenylene ether as the base polymer and B) a monomer of the general formula I as the graft monomer, in which the substituents have the following meanings R is halogen or an alkoxy, alkenyloxy, aroxy or aralkoxy group having up to 25 carbon atoms, R is an alkyl, alkenyl, aryl or aralkyl group having up to 25 carbon atoms, and X is -O- or -N -, where R is hydrogen or one of the radicals mentioned under R , and C) optionally further olefinically unsaturated monomers, their preparation and their use.
