METHOD OF PRODUCING LIGHT PETROLEUM POLYMER RESINS Russian patent published in 2019 - IPC C08F240/00 C08F6/02 C08F6/08

Abstract RU 2691756 C1

FIELD: paint industry.

SUBSTANCE: invention relates to a method of producing petroleum polymer resins used to produce paintwork materials. Described is a method of producing petroleum polymer resins by polymerization of unsaturated compounds of a fraction of liquid pyrolysis products of straight-run gasolines in the presence of a catalyst system with subsequent deactivation of the catalyst system with 1,2-epoxypropane. Catalyst system contains zeolite H-ZSM-5/20 % Al₂O₃, impregnated with CoCl₂ in amount of 2.0–3.0 % of the weight of the fraction, and Al (C₂H₅)₂Cl, taken in molar ratio of 1–1.2:1 with respect to CoCl₂. Process is carried out at temperature 65–95°C for 120 minutes.

EFFECT: reduction of process duration, reduction of process temperature, as well as reduction of catalyst consumption due to possibility of its secondary use.
