发明名称 Process for production of the maleic anhydride adduct of a liquid polymer
摘要 A process for production of the maleic anhydride adduct of a liquid polymer having a maleic anhydride addition amount of 2 to 70% by weight, which comprises reacting a liquid polymer having a molecular weight of 150 to 5,000 and a viscosity of 2 to 50,000 cp at 30 DEG C in the presence of at least one compound, as a gelation inhibitor, selected from the group consisting of imidazoles, thiazoles, metallic salts of mercaptothiazoles, urea derivatives, naphthylamines, nitrosamines, iron, iron compounds and specific halogen compounds, said liquid polymer being selected from the group consisting of liquid polybutadienes, liquid polyisoprenes and liquid copolymers comprising units of butadiene or isoprene and units of at least one compound selected from the group consisting of other diolefins, olefins and aromatic vinyl compounds.
