ABSTRACT:
A process for producing a maleic anhydride adduct of high molecular weight 1,2-polybutadiene by contacting with heat maleic anhydride with high molecular weight 1,2-polybutadiene in the absence of a radical initiator in a halogenated aromatic hydrocarbon solvent. The adduct obtained by this process has a high molecular weight of more than 10,000 and is quite free from gel. Said process enables the addition of maleic anhydride in any desired proportion.
