ABSTRACT:
Viscous polybutenes of number average molecular weight (M.sub.n) in the range of about 300 to 3000 have improved reactivity with intramolecular anhydrides of unsaturated aliphatic dicarboxylic acids when reacted in the presence of rather small amounts, i.e., 5 to 200 ppm, of alpha halogen-containing, preferably chlorine or bromine-containing, aliphatic or aromatic carbonyls including acetals as additives. Use of such halogen-containing additives in the addition reaction of polybutene with said unsaturated anhydrides can reduce formation of undesired tarry product resulting from polymerization and/or thermal decomposition of the unsaturated anhydrides.
