Synthesis of alkenylsuccini anhydrides (ASAs) was carried out in thermostable ampules at 230/sup 0/C in the course of 12 hours at an MA:PB molar ratio of 1.3:1 in a medium of prepurified petroleum xylene (30%). Freshly distilled maleic anhydride and industrial specimens of polybutene were used in the experiments. It was established that the main impurities which are formed in the production of polybutene and in its processing are ions of sodium, peroxide compounds and products of decomposition of the polymerization catalyst. The concentration of sodium ion was determined by an atomic adsorption method on an A-3000 instrument, the concentration of peroxides was determined by iodometry (3), and the concentration of catalyst decomposition products was determined from the amount of mechanical impurities.
