POLYMER PROPPANT MATERIAL AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC C09K8/80 E21B43/267 C08F132/06 C08G61/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a polymer proppant material which is a metathesis-radially cross-linked mixture of oligocyclopentadienes and methylcarboxy norbornene esters. Described is a method of producing said material, which includes preparing a mixture of oligocyclopentadienes and methylcarboxy norbornene esters by cross-linking dicyclopentadiene with methacrylic esters and polymer stabilisers given in claim 2 of the invention, heating said mixture to temperature of 150-220°C and holding at said temperature for 15-360 min, followed by cooling to 20-50°C. A radical initiator and a catalyst given in claim 2 of the invention are successively added to the obtained mixture of oligocyclopentadienes and methylcarboxy norbornene esters. Further, the obtained polymer matrix is heated to temperature of 50-340°C, held at said temperature for 1-360 minutes and then cooled to room temperature.

EFFECT: high heat resistance of the proppant material.
