COMPOSITION FOR PREPARING POLYMER MATRIX CONTAINING POLYDICYCLOPENTADIENE FOR PRODUCING COMPOSITE, POLYDICYCLOPENTADIENE COMPOSITE AND METHOD FOR PRODUCING IT Russian patent published in 2015 - IPC C08F236/14 C08L45/00 C08K5/541 C08K3/04 C08J3/24 

FIELD: chemistry.

SUBSTANCE: composition for preparing a polymer matrix contains, wt %: polymeric modifier 0.5-20.0, radical initiator 0.1-4.0, polymer stabiliser 0.1-4.0, modifying additive 1.0-15.0, ruthenic catalyst of metathesis polymerisation of dicyclopentadiene 0.001-0.02 and dicyclopentadiene min. 98% purity - the rest. The polydicyclopentadiene composite contains carbon-containing inorganic filler, organic-silicone modifier and polymer matrix described above in the preset mixture ratio. The composite is produced by preparing the polymer matrix by mixing dicyclopentadiene with polymer stabiliser and modifier, heating the prepared mixture to temperature 60-180°C and keeping the mixture at the given temperature for 2-360 min. After the mixture is cooled to 0-50°C, mixed with radical initiator, modifying additive and catalyst and agitated, the produced matrix is combined with reinforcing carbon-containing inorganic filler pre-treated with organic-silicone modifier. The polymerisation represents heated in a mould to 120-300°C and keeping at the above temperature for 1-300 min.

EFFECT: improving characteristics of the polydicyclopentadiene and reinforcing carbon composites reflected by increasing bending and tensile strength and elastic modulus, and ease of manufacturing ensured by using thermally activated carbene complexes of rhutenium.
