METHOD OF PRODUCING POLYDICYCLOPENTADIENE AND MATERIALS BASED ON SAID COMPOUND Russian patent published in 2010 - IPC C08F132/06 C08G61/08 C08F4/80 B01J23/46 C08K5/10 C08K5/134 

FIELD: chemistry.

SUBSTANCE: invention describes a method of producing polydicyclopentadiene (PDCPD) by mixing diclopentadiene (DCPD) with a catalyst in molar ratio of catalyst to DCPD ranging from 1:70000 to 1:1000000 and polymerisation by heating the reaction mixture from 30°C to 200°C. Described also is a method of producing polymer materials based on PDCPD, involving further addition of modifying additives selected from cycloolefin comonomers, cyclopentadiene oligomers in form of a mixture of trimmers and tetramers, dicarboxylic acid esters, alkylphenols or combinations thereof. The catalyst used for production of PDCPD and polymer materials based on PDCPD is a compound of formula: where L is a substitute selected from the group:

, , , , , .

EFFECT: low catalyst consumption, possibility of controlling time for onset of polymerisation, improved physical and mechanical properties of the obtained product.
