FIELD: chemistry, technology of organosilicon polymers.
SUBSTANCE: invention relates to chemistry and technology of organosilicon polymers. An organosiloxane copolymer of the general formula (I) is proposed, where n is an integer or fractional number from 79 to 84.99, m is an integer or fractional number from 10 to 20, z is an integer or fractional number from 0.01 to 1, n+m+z=100, x=1-100, R=-CH3 or -CH=CH2, a method for obtaining it, as well as a method for obtaining frost-resistant rubber based on it.
EFFECT: a new level of availability of siloxane frost-resistant rubbers with low glass transition temperatures and the absence of crystallization processes, using the developed formula of siloxane frost-resistant rubber, which is technologically advanced and corresponds to a given structure.
