MATERIAL FOR PROPPANT AND METHOD OF ITS OBTAINING Russian patent published in 2014 - IPC C09K8/80 C08F32/00 E21B43/267 

FIELD: chemistry.

SUBSTANCE: method of obtaining a material for a proppant includes obtaining a mixture of oligocyclopentadienes with a content of trimers and tetramers of 5-60 wt % by heating dicyclopentadiene to a temperature of 150-220°C and stand at the said temperature for 15-360 min, cooling of the mixture to 20-50°C, successive introduction into the obtained mixture of oligocyclopentadienes of the following components: at least, one of polymeric stabilisers, selected from the given group, at least, one of radical initiators, selected from the given group, at least, one of methacrylates, selected from the given group, and a catalyst - a compound of the given general formula. The components of a polymeric matrix are in the following quantities, wt %: polymeric stabiliser or mixture of stabilisers 0.1-3, radical initiator or mixture of initiators 0.1-4, methacrylate or mixture of methacrylates 0.3-30, catalyst 0.001-0.02, mixture of oligocyclopentadienes - the remaining part, the obtained polymeric matrix is heated to a temperature of 50-340°C and stood at the given temperature for 1-360 min, after that, cooled to room temperature. The material for the proppant is obtained by the claimed method.

EFFECT: increased thermal strength.
