| Abstract: | On the basis of carbofunctional oligo(??,??-bisphenoxy-trifluoropropyl(methyl)siloxanes, bisphenols, and bisphenol A bis(chloroformate), novel fluorine-containing poly(carbonate-block-siloxanes) are synthesized and characterized. The presence of trifluoropropyl groups in siloxane blocks of the copolymers decreases the sorption of hydrocarbons by 4 to 6 wt % instead of the 60 wt % for usual poly(carbonate-block-dimethylsiloxanes). Films based on fluorine-containing poly(carbonate-block-siloxanes) retain their high strength characteristics in the swollen state (??b = 20 MPa). |
