Summary:synthetic rubber industry. SUBSTANCE: described is method of preparing oligoisobutylene by polymerization of isobutylene in bulk in the presence of BF3 and moisture dissolved in isobutylene without using special modifier and solvent. Process is carried out in two stages, and selected temperature conditions with respect to stages, make it possible to obtain oligoisobutylene having narrow fraction composition. EFFECT: more efficient preparation method. 1 tbl
