FIELD: chemistry.
SUBSTANCE: catalyst of dicyclopentadiene polymerisation in the form of a ruthenium complex represents [1,3-bis-(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro(2-((2-dimethylaminoethylmethylamino)methyl))benzylidene)ruthenium of formula (I) 
The catalyst is obtained by the interaction of a ruthenium triphenylphosphine complex with 1,1-diphenyl-2-propin-1-ol in tetrahydrofurane or dioxane at a temperature of the solvent boiling in an inert atmosphere, then with tricyclohexylphosphine at room temperature in an inert atmosphere the formed indenylidene complex of ruthenium is extracted. The latter is successively subjected to interaction with 1,3-bis-(2,4,6-trimethylphenyl)-2-tricloromethylimidazolidine and 2-vinylbenzylamine, the formed product is extracted and dried.
EFFECT: extension of technological abilities in the process of polymerisation, and improvement of rheological, mechanical and thermal indices of the obtained polycyclopentadiene.
