Abstract
Abstract This invention relates to polymeric organosilicon compounds containing aryl radicals and to a method for improving the gliding or slipping properties of organic fibers treated therewith. The polymeric organosilicon compounds are represented by the formula M.sub.a R.sub.b Si{[(OSiR.sub.2).sub.n D].sub.m (OSiR.sub.2).sub.n OSiR 3-a M a } 4-a-b in which R is hydrocarbon or substituted hydrocarbon radical, D represents radicals of the formula --X.sub.a A--X.sub.a (A--X.sub.a).sub.c --, X represents the groups: ##STR1## --NR'--, --O--, --S--, --SO 2 --, --R"--, --NR'R", ##STR2## --OR"--, --SR"--, --SO 2 R", where R' is hydrogen or R, R" is a bivalent aliphatic hydrocarbon radical, A is a bivalent or substituted bivalent aromatic hydrocarbon radical, M represents radicals of the formula --X.sub.a --A--X.sub.a (A--X.sub.a).sub.c H, a is 0 or 1, b is 0, 1 or 2, c is 0 or a number of from 1 to 5, m is 0 or a number of from 1 to 20, n is a number of from 1 to 1,000 with the proviso that at least one OSiR 2 --unit and at least one X a --A--X a --A group must be present for each molecule.
