CATALYST OF METATHESIS POLYMERISATION OF DICYCLOPENTADIENE AND METHOD OF OBTAINING THEREOF Russian patent published in 2015 - IPC C08F4/80 C07F15/00 B01J23/46 B01J31/18 C08F32/00 C08G61/08 C08K5/56 

FIELD: chemistry.

SUBSTANCE: catalyst of polymerisation has the general formula (I)

where a novel substituent is selected from the group of aminostyrenes. It ensures fundamentally novel properties of the catalyst. The catalyst is obtained by the interaction of a triphenylphosphine complex of ruthenium with 1,1-diphenyl-2-propin-1-ol in tetrahydrofuran or dioxane at a temperature of the solvent boiling in an inert atmosphere, and then with tricyclohexylphospine at room temperature in an inert atmosphere, the formed ruthenium indenylidenic complex is extracted. The latter is successively subjected to interaction with 1,3-bis-(2,4,6-trimethylphenyl)-2- tricloromethylimidazolidine and respective aminostyrene with the formation of a target product.

EFFECT: reduction of the catalyst consumption, reduction of the time before beginning of the polymerisation process and improvement of rheological, mechanical and thermal indices of the obtained polydicyclopentadiene, which ensures obtaining the product from polydicyclopentadiene with high consumer properties.
