Abstract:
A novel antistatic agent soluble in organic solvent which can afford durable antistatic property to hydrophobic fibers and fibrous structures is provided. Such antistatic agent consists substantially of a complex compound of a polyvinyl derivative having quaternary ammonium groups in its side chains, its counter anion being substituted with an anionic surfactant containing 2 to 8 ethylene oxide units, an esterbonded sulfonate, an alkylamidocarboxylic acid salt or an amphoteric surfactant of carboxylic acid type. Hydrophobic fibers and fibrous structures having durable antistatic property, and a process for producing such hydrophobic fibers and fibrous structures also are provided, by utilizing the above antistatic agent.
Abstract:
An acid copolymer/quaternary amine mixture is disclosed which is permanently antistatic. The acid copolymer is a copolymer of (i) a major amount by mol % of an alpha-olefin of the formula RCH.dbd.CH.sub.2 wherein R is H or C.sub.1 to C.sub.8 alkyl, and (ii) a minor amount by mol % of an alpha,beta-ethylenically unsaturated carboxylic acid. The quaternary amine is of the formula [(R.sup.1)(R.sup.2)(R.sup.3)(R.sup.4)N].sup.+ [X].sup.- wherein R.sup.1 is selected from H, aryl, or C.sub.1 to C.sub.50 alkyl optionally having one or more non-contiguous C.dbd.O or NHC.dbd.O or --S-- or --O-- in the carbon chain, or the same as R.sup.2 ; each of R.sup.2, R.sup.3, and R.sup.4 is the same or different and selected from H, C.sub.1 to C.sub.18 alkyl optionally substituted with one or more OH or from --(R.sup.5 --O).sub.a --H where a is an integer from 1 to 10 and R.sup.5 is ethylene or propylene; and X is an anion selected from chloride, bromide, iodide, fluoride, nitrate, fluoborate, phosphate, C.sub.1 to C.sub.8 alkyl phosphate, sulfate, C.sub.1 to C.sub.8 alkyl sulfate, formate, C.sub.1 to C.sub.8 alkyl or C.sub.6 to C.sub.24 alkaryl or aryl sulfonate, acetate, citrate, trifluoroacetate, propionate, tartrate or carbonate.
