FIELD: chemistry. n SUBSTANCE: invention relates to technology of production of reinforcing filaments, namely, filaments in form of glass braids, covered with appret composition in form of water or water-free dispersion. Composition includes, at least one silane of general formula Si(R 1 )(R 2 )(R 3 )(R 4 ), where - R 1 , R 2 and R 3 are selected from: -H (except R 3 ), -Cl, -O-R 5 , -O-R 6 -O-R 5 , -O-(C=O)-R 5 , -O-R 6 -(C=O)-R 5 ; R 5 and R 6 - radicals, in which main chain contains 1-4 atoms of carbon; - R 4 = -R 7 -NHR 8 ; R 7 - radical, branched with at least two side chains, and main chain contains from 2 to 6 atoms of carbon; R 8 = -H, -R 9 -NH 2 , -R 10 -NH-R 9 -NH 2 ; R 9 - radical, containing from 1 to 12 atoms of carbon, or carbonyl; and R 10 - radical, in which main chain contains from 1 to 6 atoms of carbon. n EFFECT: production of reinforcing filaments and composites, resistant to aggressive medium. n 9 cl, 3 ex |
