METHOD FOR PREPARING OF RAW MATERIALS FOR PRODUCTION OF LIGHT PETROPOLYMER RESINS

摘要

FIELD: petrochemistry. SUBSTANCE: during heat treatment of C₅ fraction (being isolated of products of pyrolysis of raw petroleum) low molecular weight polybutylene is used as additive, its quantity being 0.1-1 mass % as calculated for raw materials. Mentioned above heat treatment is carried out at 120-180 C, it is followed by distillation fraction having boiling away temperature up to 130 C and by isolation of desired product. Desired product contains 88-89.5 % of resin-forming components. EFFECT: simplifies the method, decreases energy expense.
