    Abstract

    FIELD: polymer materials. SUBSTANCE: invention provides novel polysiloxane block copolymers of formula T(AB)xAT, in which A is polysiloxane block, B polyalkylen oxide block, and T polyalkylen oxide block with terminal unsaturated groups. Block copolymers are prepared by reaction of hydride derivative of polysiloxane with polyalkylen oxide with terminal unsaturated groups in presence of catalyst. EFFECT: enabled controlling polarity of block copolymers to produce elastomers. 6 cl, 3 ex
