FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing an alkenyl-substituted cyclic anhydride, comprising the following steps: isomerising one or more olefinically unsaturated C6-C28 hydrocarbons, from which at least 30 wt % is alpha-olefin, by contacting said hydrocarbons with a catalyst which contains an alkali metal on a support, and reacting the formed isomerised C6-C28 olefin hydrocarbons with a cyclic anhydride of an unsaturated dicarboxylic acid to form an alkenyl-substituted cyclic anhydride.
EFFECT: invention relates to use of said compound as a paper sizing additive and a method of producing said additive based on the obtained alkenyl-substituted cyclic anhydride.
