FIELD: chemical technology. ^ SUBSTANCE: invention relates to a method for preparing petroleum-polymeric resins and can be used in chemical, petroleum and paint-varnish industry. Invention involves simplifying the technology for preparing petroleum-polymeric resins, in particular, simplifying stage of catalyst neutralization, improvement of ecology process due to reducing amount of sewages and solid slimes. Method involves preparing petroleum-polymeric resins by polymerization of unsaturated compounds in fraction of liquid pyrolysis products of directly distilling gasolines with evaporation limit points 130-190 C in the presence of titanium tetrachloride, tin tetrachloride and catalytic system - titanium tetrachloride and organic-organic compound taken in the following 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). Then neutralization of catalyst is carried out with epichlorohydrin taken in the stoichiometric amount to catalyst. ^ EFFECT: improved preparing method. ^ 1 tbl |
