METHOD OF PRODUCING POLYMERIC PETROLEUM RESINS Russian patent published in 2009 - IPC C08F240/00 C08F6/02 

FIELD: chemistry.

SUBSTANCE: present invention refers to method of producing polymeric petroleum resins. There is disclosed method of producing polymeric petroleum resins by polymerising unsaturated compounds of liquid pyrolysis product fraction of straight-right gasoline of boiling range 130-190°C with catalyst system added: titanium tetrachloride and organoaluminium in mole ratios: TiCl₄: Al(C₂H₅)₂Cl =1:(0.1-10); TiCl₄: Al(C₂H₅)₃ = 1:(0.1-10); TiCl₄: Al(iso-C₄H₉)₃ = 1: (0.1-10), characterised that catalyst is neutralised with diepoxides of general formula: , where n=0-2, so that epoxide groups is equivalent to total amount Cl-, C₂H₅- and iso-C₄H₉-groups in titanium and aluminium atoms of catalyst system components.

EFFECT: simplified technology of polymeric petroleum resins, specifically simplified catalyst neutralisation stage, improved ecological compatibility of process, and reduced cost price of polymerisation products.
