FIELD: chemistry.
SUBSTANCE: invention relates to application of polyorganosiloxane with 3 or more elementary siloxane links, which contains one or more organic components R1, with R1 containing one or more carbon-carbon bonds and is selected from cycloalkenyl, alkenyl, vinyl, alkyl, norbornyl, (di)cyclopentyl or methacrylate or acrylate derivatives, and one or more hydrocarbon components R2, with R2 having chain length from 5 to 50 carbon atoms, as additive in rubber recycling, where recycling represents peroxide vulcanisation. Amount of applied polyorganosiloxane constitutes from 0.5 to 10 parts per 100 parts of rubber.
EFFECT: polyorganosiloxanes lead to reduction of viscosity in rubber recycling and in case of necessity to improvement of mechanical properties of vulcanised rubber.
