    摘要: It has been suggested that antistatic properties of fibers of polyamide could be improved by dispersing in the polyamide a small proportion of a reaction product of a tetrol compound represented by the formula:

    WHERE A, B, C, D, E, F, G, AND H ARE EACH A WHOLE NUMBER AND A is a difunctional radical from a hydrocarbon containing 1 to 13 carbon atoms, said tetrol compound having a molecular weight between about 4,000 and about 50,000, and at least one compound selected from the group consisting of diepoxides and compounds which yield the following divalent radicals:

    WHERE A'' is a difunctional radical from a hydrocarbon containing 1 to 30 carbon atoms. However, with incorporation of this antistatic additive in the polyamide, serious problems have been encountered in meltspinning due to the frequent occurrence of ''''nubs'''' or enlarged places in the extruded polyamide filament. It has now been found that the occurrence of said nubs in the antistatic polyamide fiber can be greatly reduced by dispersing in the polymer an additional small proportion of a hindered phenol represented by the formulae:

    IN WHICH X HAS A VALUE OF FROM 1 TO 6 AND Y HAS A VALUE OF FROM 6 TO 30; AND

    IN WHICH R is

    WHEREIN X'' HAS A VALUE FROM 1 TO 6 AND Y'' HAS A VALUE OF 1 TO 6. When the term ''''alkyl'''' is qualified by the designation ''''(lower),'''' there is intended a branched or straight chain hydrocarbon of from 1 to about 6 carbon atoms. Preferably, the phenol compound is used with at least 0.1% by weight, based on the weight of the antistatic additive, of a sulfur compound of the formula:

    WHEREIN R'''' is an alkyl radical containing 8 to 18 carbon atoms and n is 1 to 3.

    摘要: An antistatic polyolefin composition comprises a polyolefin mixed with a N,N-bis-(hydroxyalkyl) fatty acid amide and an ionic salt of a monovalent metal. The preferred amides are of the formula where n is 7 to 17 and R and R1 are alkylene radicals of 1 to 4 carbon atoms. The amide and salt are preferably present in amount of 0.1 to 1.0% by weight of the polymer, the preferred weight ratio of amide to salt being from 1:1 to 10:1. The preferred monovalent metal is an alkali metal, e.g. lithium, potassium and sodium the preferred salts being halides, thiocyanates, nitrates, nitrites, phosphates, organosulphonates and carboxylates of up to 18 carbon atoms. In the examples, N,N-bis-(hydroxyethl) lauramide, N,N - bis - (hydroxyethyl) stearamide and N,N - bis - (hydroxyethyl) caprylamide are employed. The salts used in the examples are sodium acetate, sodium butyrate, sodium caprylate, sodium laurate, sodium stearate, lithium acetate, potassium thiocyanate, sodium nitrite, potassium toluene sulphonate, sodium methane sulphonate, sodium nitrate, sodium dibutyl phosphate and potassium bromide. Polymers used in the examples are polyethylene, polypropylene and a copolymer of propylene and ethylene.
