摘要:
The invention describes a storage-stable aqueous emulsion comprising a) a compound of the formula (I); wherein n is 4 to 23, b) a surfactant, and c) water, and describes a storage-stable liquid blend with low viscosity, which is not an aqueous emulsion, comprising a) a compound of the formula I d) at least a stabilizer selected from the group consisting of phosphites, phosphonites, aminic antioxidants, hydroxylamines, benzofuran-2-ones, thiosynergists, plasticizers, acid scavengers, lubricants, dispersing aids, sterically hindered amines, UV absorbers and sterically hindered phenols other than the compounds of the formula I according to component a). These emulsions and blends are useful as stabilizers for organic materials.

摘要:
Recycled mixed plastics from domestic and commercial waste can be stabilized against thermal oxidative degradation by adding a combination of a sterically hindered phenol with a phosphite or phosphonite.
摘要:
Organic materials which possess outstanding stability to oxidative, thermal or light-induced degradation comprise as stabilizers at least one compound of the benzofuran-2-one type and at least one compound of the sterically hindered amine type.
摘要:
Described are compositions comprising (a) 25 to 99% of organic phosphite or phosphonite, based on the total weight of the composition, (b) an effective stabilizing amount of organic amine, and (c) an effective stabilizing amount of acid-binding metal salt, wherein said composition comprises no organic polymers or alkali metal phosphates as further components, as well as a process for stabilising organic phosphites or phosphonites against hydrolysis by addition of organic amine and acid-binding metal salt. The compositions are distinguished by their excellent stability to hydrolysis and have good storage stability even at high atmospheric humidity. The novel compositions and process products can be used with advantage as stabilisers for organic material against the harmful action of heat, oxygen and/or light.
摘要:
Polyolefin fibers and filaments, and fabrics made therefrom, are rendered dyeable via a combination of dyeability additives. The dyeability additive combination comprises at least one compound selected from the group consisting of the polyamides, copolyamides and polyetherpolyamides and at least one ethylene vinyl acetate. The dyed polyolefin fibers and fabrics are rendered light stable via the use of a combination of stabilizers, which comprises at least one compound selected from the group consisting of the ultraviolet light stabilizers and at least one compound selected from the group consisting of the hindered amine light stabilizers. The ultraviolet light stabilizers are for example hydroxyphenylbenzotriazoles or tris-aryl-s-triazines. The hindered amine light stabilizers are for example of high molecular weight, for instance greater than 1000 g/mol. The dyes are for example anthraquinone blue dyes, anthraquinone red dyes, diazo red dyes or nitro yellow dyes.
摘要:
The invention relates to stabilized filled polyolefins comprising a filler and a macrocyclic compound which contains a radical of formula ##STR1## in the macrocyclic structure or in a side-group, said macrocyclic structure consisting of at least 8 atoms and wherein the substituents R are each independently of one another methyl, ethyl or propyl, or two substituents R at the same carbon atom are together also a pentamethylene radical, and a is 0, 1 or 2. The invention also relates to a method of stabilizing filled polyolefins and to the use of the macrocyclic compounds as stabilizers.
