Abstract: A process for preparing polyamides comprises polymerizing starting monomers or starting oligomers in the presence of at least one compound of the formula (I)whereR is a functional group R which bears 1-4 identical or different amide-forming groups R ,R is H, C1-C20-alkyl, cycloalkyl, benzyl or OR , where R is H, C1-C20-alkyl, cycloalkyl or benzyl,R , R , R and R are independently C1-C10-alkyl,n is a natural number greater than 1, andthe piperidine derivatives attached to R are identical or different with regard to the substituents, meaning R , R , R , R and R .The polyamides are useful for preparing filaments, fibers, films, sheetlike structures and moldings.

Abstract: PCT No. PCT/EP97/02822 Sec. 371 Date Nov. 12, 1998 Sec. 102(e) Date Nov. 12, 1998 PCT Filed May 30, 1997 PCT Pub. No. WO97/46529 PCT Pub. Date Dec. 11, 1997A process for purifying crude piperidines of the formula I where R1 to R4 are C1-C6-alkyl, or R1 and R2 and/or R3 and R4 together are a CH2-chain of 2 to 5 carbons, which comprises, in a first step, removing high-boiling substances and, if present, water from the crude piperidines by distillation; in a second step, adding from 0.01 to 5% by weight, based on the product of the first step, as a reducing agent; and, in a third step, isolating the piperidines by distillation.

Abstract: An inherently light- and heat-stabilized polyamide has at least one piperidine compound bonded to the backbone polymer chain and at least one 4-amino-2,2,6,6-tetramethylpiperidine compound bonded to the backbone polymer chain. The inherently light- and heat-stabilized polyamide may be used to form articles such as, for example, fibers, carpets, yarns, and textile fabrics.

Abstract: Compounds of the general formula Iwheren is 0 or 1,Z is a straight-chain or branched polyalkyl radical having a number average molecular weight of from about 150 to 40,000, andY is a radical of the formula IIa or IIb wherethe radicals R, R1 and R2 independently of one another, are each hydrogen, an unsubstituted or substituted alkyl, alkenyl or alkynyl radical or an unsubstituted or substituted cycloalkyl, aryl or arylalkyl radical, which may carry one or more heteroatoms, andA is an alkyleneimine radical; or, ifn is 0, one of the radicals Y may be a polyoxyalkylene radical,and processes for their preparation and fuel and lubricant compositions, and mixtures of additives, which contain the novel compounds.
