Abstract

A new composition has been found comprising an antistatic fiber selected from the group consisting of polyamide, polyester, polyurea, polyurethane, or polysulfonamide, said fiber containing between about one percent and about twelve percent by weight of at least one compound having a molecular weight above 1500 selected from the group consisting of compounds represented by the formulas: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently selected from nonovalent hydrocarbon radicals having 1 to 20 carbon atoms derived from aliphatic, aromatic, cycloaliphatic, aromaticaliphatic, heterocyclic hydrocarbons or --(C.sub.r H.sub.2r O).sub.m (C.sub.p H.sub.2p O).sub.q --H; R.sub.5 is at least one of the alkylene difunctional radicals having 2 to 15 carbon atoms and a radical selected from ##STR2## R.sub.6, R.sub.7, R.sub.8 and R.sub.9 are independently selected from R.sub.1, R.sub.2, R.sub.3, R.sub.4, H or another monovalent hydrocarbon radical having 1 to 20 carbon atoms as defined for R.sub.1, R.sub.2, R.sub.3, R.sub.4, PA1 provided that at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6, R.sub.7, R.sub.8, or R.sub.9 is --(C.sub.r H.sub.2r).sub.m (C.sub.p H.s…
