FIELD: organosilicon polymers. ^ SUBSTANCE: invention provides novel polysodiumoxyorganosiloxanes depicted by general formula XO-[Si(ONa)(R)-O]n-X, wherein R represents CH3 or -CH2=CH, or C6H5; n varies from 4 to 2000; X represents single bond or -H and/or -Alk = CH3, C2H5, or i-C3H7. These novel polysodiumoxyorganosiloxanes are prepared via hydrolytic polycondensation of sodiumoxyorgano(dialkoxysilane) selected from the series of compounds having general formula AlkO-Si(ONa)(R)-O-OAlk (wherein R is the same as above) in organic solvent medium and in presence of stoichiometric amount of water. ^ EFFECT: expanded synthetic possibilities in organosilicon polymer area. ^ 14 cl, 4 dwg, 1 tbl, 6 ex |
