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 MaRbSi{[(OSiR2)nD]m(OSiR2)nOSiR3-dMd}4-a-b in which R is hydrocarbon or substituted hydrocarbon radical, D represents radicals of the formula -XaA-Xa(A-Xa)c-, X represents the groups: <IMAGE> <IMAGE> 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 -Xa-A-Xa(A-Xa)cH, a is 0 or 1, b is 0, 1 or 2, c is 0 or a number of from 1 to 5, d is 0 or 1, 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 OSiR2- unit and at least one Xa-A-Xa-A group must be present for each molecule.
