PETROLEUM POLYMER RESINS Russian patent published in 2007 - IPC C08F240/00 C08F4/68 

FIELD: polymer production.

SUBSTANCE: invention relates to production of petroleum polymer resins useful in petrochemical industry and in production of lacquer materials. Petroleum polymer resins are obtained via initiated polymerization of C₉ fraction of pyrolysis condensate distillation in presence of three-component initiation system, namely a mixture of organic peroxides having various half-life temperatures, of which two peroxides with low half-life temperatures are added in the beginning of the process and third one having higher low half-life temperature is added during all the polymerization process.

EFFECT: increased yield of product and improved its quality.
