    摘要: The invention relates to the use of oligomeric carbodiimides containing at least one heterocyclic end group as stabilizers for polymers. The oligomeric carbodiimides can be compounds of the general formula (I), in which A1, A2 are identical or different and represent hydrocarbon groups with 2 to 20 carbon atoms independently of each other; B1, B2 are identical or different and represent heterocycles, C1-C30 alcohols, poyletherols, polyesterols, amines, polyetheramines, polyesteramines, thioalcohols, polyetherthiols, polyesterthiols independently of each other; R1, R2 are identical or different and represent (A) independently of each other; and n represents a whole number ranging from 2 to 100; wherein A1, A2, B1 and B2 can each be substituted with C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C1-C20 alkoxy, carbonyl oxygen (=O), or halogen at any position with the proviso that at least one substituent of B1 or B2 is a heterocyclic end group. The invention further relates to methods for stabilizing polymers against hydrolysis using oligomeric carbodiimides.

    摘要: The invention relates to a printable composition which has a viscosity of 1 - 1000 mPas and comprises a) 5 - 50 % by weight of super-absorbent polymer particles, b) 10 - 40 % by weight of at least one organic, water-insoluble binder, c) 0 - 10 % by weight of at least one additive, and d) 40 - 80 % by weight of at least one organic solvent. The invention also relates to printed planar materials having at least one surface imprinted with the printable composition, and to the use of the printed planar materials for packaging food items, for packaging moisture-sensitive products, for moisture control in buildings or as membrane in textiles.

    摘要: The invention relates to a mixture containing at least one multi-functional chain extender with at least three reactive groups, as well as at least one monofunctional or difunctional hydrolytic stabiliser, said chain extender and hydrolytic stabilisers reacting with the end groups of polymers when the polymers are in a melted or solid state, with a chemical bond being formed. The invention also relates to the use of such mixtures as stabilisers for polymers, and to a method for the stabilisation of polymers against losses in molecular weight in which an effective amount of such a mixture is added to the polymer.
