METHOD OF PRODUCING POLYMERIC PETROLEUM RESIN Russian patent published in 2011 - IPC C08F240/00 C08F6/02 

FIELD: chemistry.

SUBSTANCE: 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 a catalytic complex of AlCl₃:C₁-C₅ alcohol:C₂-C₅ carbonyl compound:water in molar ratio equal to 10.0-98.0:0.9-5.2:1.7-7.0:1.0,characterised by that, the catalyst is deactivated with triglycidyl ethers of polyoxypropylenetriols manufactured under the Laproxide 603 and Laproxide 703 brands, having general formula: where a, b, c=1-3, with molecular weight 434-782, taken in equimolar ratio to 100% AlCl₃ in the catalytic complex, which corresponds to an equimolar amount of epoxide groups to the amount of Cl to aluminium. The deactivation products remain in the polymeric petroleum resin.

EFFECT: improved environmental friendliness of the process of producing polymeric petroleum resins, elimination of the explosion hazard and inflammation during deactivation of components of the catalytic complex.
