METHOD OF PRODUCING POLYMERIC PETROLEUM RESIN Russian patent published in 2010 - IPC C08F240/00 C08F6/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing polymeric petroleum resins. The invention describes a method of producing polymeric petroleum resins which involves polymerisation of unsaturated compounds of the fraction of liquid products of pyrolysis of straight-run petrol with boiling range of 130-190°C in the presence of catalyst systems: titanium tetrachloride and an organoaluminium compound in molar ratio: TiCL₄ : Al(C₂H₅)₂Cl = 1:(0.1-3.0); TiCl₄ : Al(C₂H₅)₃ = 1:(0.1-3.0); TiCl₄ : Al(iso-C₄H₉)₃ = 1:(0.1-3.0).The method is distinguished by that the catalyst is deactivated with triglycidyl ethers of polyoxypropylenetriols manufactured under the trademark Laproxide 603 and Laproxide 703, having general formula:

, where a, b, c = 1-3, with molecular weight of 434-782, and taken in molar ratio to the catalyst system of 1.0:2.1.The deactivation products remain in the composition of the polymeric petroleum resins.

EFFECT: simple technology of producing polymeric petroleum resins, improved environmental safety of the process, improved sanitary and hygienic conditions during production.
