METHOD OF PREPARING HYDROCARBON RUBBER ADHESIVE USING FLUOROHYDROCARBON DILUENT Russian patent published in 2012 - IPC C08F6/00 C08F6/24 C08C1/02 C08L21/00 C08L23/00 

FIELD: chemistry.

SUBSTANCE: method of preparing an essentially homogeneous hydrocarbon rubber adhesive with a single liquid phase from a polymer suspension containing hydrocarbon rubber, where the hydrocarbon rubber contains a polymer (polymers) and/or a copolymer (copolymers) of isobutylene, isoprene, para-methylstyrene or combination thereof, a diluent and an unreacted monomer (monomers) involves the following steps: (a) bringing the polymer suspension into contact with a hydrocarbon solvent and (b) removing the diluent and solvent in amounts which are not higher than needed to prepare an essentially homogeneous hydrocarbon rubber adhesive with a single liquid phase. The weight fraction of the monomer (monomers) in the hydrocarbon rubber adhesive based on the total amount of hydrocarbon rubber contained in the hydrocarbon rubber adhesive is less than that of the monomer (monomers) in the hydrocarbon rubber suspension based on the total amount of hydrocarbon rubber contained in the hydrocarbon rubber suspension. The diluent contains fluorohydrocarbon.

EFFECT: obtaining hydrocarbon rubber adhesive which is resistant to heat ageing and has low permeability for gases.
