Abstract:
The present invention relates to amphiphilic water-soluble alkoxylated polyalkyleneimines having an inner polyethylene oxide block comprising 20 to 50 polyethylene oxide units and an outer polypropylene oxide block comprising 10 to 50 polyethylene oxide units and especially to such alkoxylated polyalkyleneimines wherein the ratio of polyethylene oxide units and polypropylene oxide units is proportionally related to the square root of the number of polyalkyleneimine units present in the backbone. The present invention further relates to the use of these alkoxylated polyalkyleneimines as a soil detachment promoting additive to laundry detergents and cleaning compositions and to laundry detergents and cleaning compositions which comprise these alkoxylated mono- or polyalkyleneimines.

Abstract:
The present invention relates to a process for the alkoxylation of a first polymer comprising at least one monomer unit having NH groups and optionally NH2 groups, wherein the first polymer has a molecular weight Mw of at least 500 g/mol, comprising the steps of (a) reacting the first polymer with alkylene oxide in a reaction mixture comprising a solvent until the average degree of alkoxylation of each NH group and each optional NH2 group, calculated as two NH groups, is from 0.75 to 1.25; (b) adding a second polymer of formula (I), wherein R is a linear or branched alkyl group having from 1 to 20 carbon atoms, each R' is independently a linear or branched alkyl group having from 1 to 20 carbon atoms or hydrogen, each n is independently from 1 to 5 and m is from 5 to 40, to the reaction mixture of step (a); (c) at least partially removing the solvent from the reaction mixture of step (b); and (d) further reacting the reaction mixture of step (c) with alkylene oxide at a given temperature until the average degree of alkoxylation of each NH group and each optional NH2 group, calculated as two NH groups, of the first polymer is from 2 to 40. The present invention also relates to a polymer composition obtainable from that process and the use of such a polymer composition.
Abstract:
The invention relates to the use of specific benztriazole derivatives of general formula (I), wherein B represents an optionally substituted 2-(2-hydroxyphenyl)- 2H-benztriazole group, n is a whole number between 3 - 20 and A represents an n-valent organic radical, as a UV-absorber or stabiliser in inanimate organic materials. The invention also relates to methods for stabilising inanimate organic materials, in particular plastics, counter to the effects of light by means of specific benztriazole derivatives. The invention also relates to specific benztriazole derivatives and inanimate organic materials containing specific benztriazole derivatives.
