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: Dien-1-ols of the general formula I (I) where the radicals R1 to R7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II (II) in the presence of an acidic catalyst at elevated tempertures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10-enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10-dodecadienol.
