FIELD: organosilicon polymers.
SUBSTANCE: invention provides polysiloxane-polycarbonates giving general formula: 
, wherein Z represents (O)CCH2=CH2 or (O)C(CH3)C+CH2; R - (CH3)2C(C6H4)2; R1 - CH3, C2H5, or C6H5; R2 - H, CH3, CH=CH2, CH3(OCH3)2SiCH=CH2, CH2O(O)C(CH3)C=CH2, or (CH2)3O(O)C(CH3)C=CH2; A - C6H4; B - CH-CH; Y - Cl, Br, or NO2; X - CH2, C(CH3)2, C(CF3)2, C(CH3)C6H5, SO2, or N=N(O); a=25-50, b=1-5, 0<m<1, n+d+k=1, p=1-30. Method of preparing these polymers is also disclosed.
EFFECT: achieved high strength, and elastic, and x-ray contrast characteristics of polysiloxane-polycarbonates enabling employment thereof in manufacturing thin film membranes and other various-destination elastic products.
