PROCESS FOR PREPARING CYCLOLINEAR SILOXANE BLOCK COPOLYMERS Russian patent published in 1997 - IPC

Abstract RU 2081128 C1

FIELD: substrate for sealing and priming compositions and anticorrosion coatings. SUBSTANCE: cyclolinear siloxane block copolymers are prepared by heterofunctional condensation of methyl trisiloxane excess with α, ω-potassium dimethyl siloxane diolate with polymerization degree of 198 followed by hydrolytic polycondensation of resulting oligochlorosiloxane in the presence of saturated potassium carbonate solution. EFFECT: higher efficiency. 1 tbl
