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

FIELD: chemistry.

SUBSTANCE: method of a proppant obtaining includes obtaining a mixture of oligocyclopentadienes by heating dicyclopentadiene to a temperature of 150-220°C and stand at the said temperature for 15-360 min, cooling of mixtures to 20-50°C, successive introduction into the obtained mixture of oligocyclopentadienes of the following components: at least, one of polymer stabilisers, selected from the given group, at least, one of radical initiators, selected from the given compounds, or their mixture, and catalysts - a compound of the given formula, with components of a polymer matrix being present in the following quantities, wt %: polymer stabilisers 0.1-3; radical initiators 0.1-4; catalyst 0.001-0.02; mixture of oligocyclopentadienes - the remaining part, the obtained polymer matrix is kept at a temperature of 20-50°C for 1-40 minutes, after that, in the form of a laminar stream it is introduced into water preliminarily heated to not less than the temperature of the matrix, which contains SAS from the given group, where a mixture of water with SAS has a viscosity of the polymer matrix, in the process of constant mixing water is heated to 50-100°C, with continuation of mixing for 1-60 min, the formed microspheres are separated from water, heated in a medium of an inert gas to a temperature of 150-340°C and kept in the said medium at the said temperature for 1-360 min. The polymer proppant is obtained by the claimed method.

EFFECT: increased thermal strength.
