    Abstract: A thermoplastic addition polymer contains as antistatic additive a compound wherein R1, R2, R3 and R4 are hydrocarbon radicals and X is -O- or >NH. Specified polymers are polyvinyl chloride, polyethylene, polypropylene and styrene polymers (optionally containing elastomer). In examples, the additives used are N-lauroyl-N1-dimethyltrimethylene diamine, (Beta-diethylaminoethyl) stearate, N - lauroyl - N1 - diethyl - alpha -methyltetramethylene diamine, the reaction product of montanic acid and N,N-dimethylaminopropylamine, N - oleoyl - N1 - dimethyltrimethylene diamine, dibutylamino - isopropyl oenanthate and N-lauroyl-N1-dimethylamino-trimethylene diamine.

    IPC: C08K5/20

    Abstract: Moulding materials based on polyethylene having a density of 0.915 to 0.940 g./cm.3 contain as an antistatic agent 0.01 to 5% by weight of an amide of the formula R-CONR1R2 in which R denotes an aliphatic hydrocarbon radical having 7-29 carbon atoms, R1 denotes H or R2, and R2 denotes the group -(A-O)m-(B-O)n-(D-O)pH, in which A, B and D are the same or different alkylene radicals of 2-4 carbon atoms, and the total of m+n+p is an integer of from 8-22 when R1 is H and an integer of from 4-11 when R1=R2. Additives such as fillers, dyes, light stabilizers, heat stabilizers, lubricants and anti-blocking agents (all unspecified) may also be included. Products such as film, sheeting, sections and household articles may be obtained from the moulding material which is generally in granular form.

    Abstract: Tyre cords are made of linear polyamides containing as stabilizer, between 0.01 and 5% by weight of a condensation product of formaldehyde and one or more monophenols having the general formula in which R1 is an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 6 to 8 carbon atoms, an aralkyl group having 7 to 10 carbon atoms or an aryl group and R2 is hydrogen, an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 6 to 8 carbon atoms, an aralkyl group having 7 to 10 carbon atoms or an aryl group. Specified monophenols are p-tertiary butyl phenol, p-isopropylphenol, diisopropylphenol, p - cyclo-octylphenol, p - cyclo-hexylphenol, p-phenylphenol, p-heptylphenol, p-octylphenol, p-dodecylphenol, o-methyl-p-tertiary-butyl phenol and 2-(p-hydroxyphenyl)-2-phenyl propane. Specified linear polyamides are those derived from adipic acid and xylylene or hexamethylene diamine, pyrrolidone, piperidone, #z-caprolactam, caprylolactam, dodecylolactam and undecylolactam. The stabilizers may be added to the polyamide-forming monomers or mixed with the polyamides. In the examples: (1) #z-caprolactam is polymerized in the presence of polymers made from formaldehyde and (a) p-t.-butylphenol, (b) p-dodecylphenol, (c) p-isoheptylphenol, (d) p-hydroxydiphenyl, (e) isopropylphenol, (f) cyclo-octylphenol, and (g) n-octylphenol; (2) poly-#z-caprolactam is mixed with a formaldehyde-p-cyclo-hexylphenol condensate; (3) polyhexamethylene adipamide is mixed with a formaldehyde-p-hydroxydiphenyl condensate and (4) polycaprylolactam is mixed with a formaldehyde-p-hydroxydiphenyl condensate, the resultant stabilized polyamides being spun into filaments from which tyre cords are made.
