POLYDICYCLOPENTADIENE-CONTAINING MATERIAL AND METHOD FOR PRODUCTION THEREOF (VERSIONS) Russian patent published in 2012 - IPC C08F232/08 C08G61/08 C08F236/00 C08F4/80 B01J23/46 C08K5/11 C08K5/13 C08K5/17 C08K5/49 C08K7/14 

FIELD: chemistry.

SUBSTANCE: described is material (version) which contains 1-99.8 wt % polydicyclopentadiene, 0.05-0.99 wt % antioxidant selected from: sterically hindered phenols, phenol derivatives, sterically hindered amine bases, 0.05-0.99 wt % saturated or unsaturated elastomer, 0.000018-0.00010 wt % catalyst; the rest of the amount of the material is modifying additives, which can be contained both separately and together in form of their different combinations, wherein the modifying additives are selected from a group A) cyclopentene, cyclooctene, cyclooctadiene, norbornene, norbornadiene; B) cyclopentadiene trimers and/or tetramers; C) dyes; D) compounds which alter activity of the catalyst system, selected from: amines, phosphines, phosphites, phosphoramides, organoaluminium compounds; E) filler materials, selected from: chopped glass or carbon fibres with diameter of 6-17 mcm and length 4-24 m, as well as structural glass, carbon and basalt fabric with thickness of 0.20-0.87 mm and density of 250-900 g/m²; F) multi-wall carbon nanotubes with 2-20 walls and diameter of 7-30 nm. Described is a method of producing said material, which contains polydicyclopentadiene, involving mixing, in any sequence, dicyclopentadiene, catalyst, antioxidant, elastomer and modifying additives with subsequent polymeriseation of the obtained reaction mass while heating from 30 to 210°C. Described also is material (version) which contains 1-98.9 wt % polycyclopentadiene and 1-98.9 wt % "полиэндикатов", and containing an antioxidant, an elastomer, a catalyst and modifying additives, the quality and amount of which correspond to said version of the material. Described is a method of obtaining said material, which involves further addition of "полиэндикатов" to the reaction mass before polymerisation.

EFFECT: high impact viscosity and glass-transition temperature of the obtained material owing to addition of small amounts of elastomer into the reaction mass, reduced amount of antioxidant used, high rate of polymerisation and possibility of using starting material with different purity.
