摘要:
Process for the preparation of products of the reaction of polyaspartimides and amino acids by reaction of amino acids with polyaspartimides in aqueous medium at pH values at which at least 5% of the amino groups in the amino acids are in non-protonated form in equilibrium with the protonated form, and use of the reaction products obtainable in this way and of products of the reaction of polyaspartimides with alkanolamines or aminated C.sub.1 -C.sub.30 -fatty alcohol alkoxylates which contain as copolymerized units up to 50 mol % of ethylene oxide and/or propylene oxide per mol of fatty alcohol, as additive to detergents and cleaners, as scale inhibitor and as dispersant.

Glycerol aminocarboxylates of the formula ##STR1## where n is from 0 to 10 andR is ##STR2## where L is iminodiacetate, aspartate, glutamate, sarcosinate, glycinate, serinate, hydroxyaspartate, ethanolaminoacetate, diethanolamino, alanate or taurinate andX is hydrogen, an alkali metal, ammonium or substituted ammonium,are prepared by esterifying glycerol or polyglycerols which contain up to 10 glycerol units with maleic anhydride or itaconic anhydride and addition of compound L-H where L is as defined above to the double bonds of the esters, and are used as complexing agents.
摘要:
2-(1-Hydroxycarbalkoxymethyl)-acrylonitriles and 2-(1-hydroxycarbalkoxymethyl)-acrylates are prepared by a process in which an acrylonitrile or an acrylate is reacted with a glyoxylate in an aqueous medium at a pH greater than or equal to 6, in the presence of a tertiary amine as a catalyst.
摘要:
2-(hydroxymethyl)-acrylonitrile and 2-(hydroxymethyl)-acrylates of the formula ##STR1## where X is --CN or ##STR2## and R is unsubstituted or substituted alkyl, are prepared by reacting acrylonitrile or an acrylate with hydrated formaldehyde or a hemiacetal of formaldehyde in the presence of a tertiary amine as a catalyst.
摘要:
A process for preparing finely divided mixtures of amphiphilic polymers and polycarboxylates, which comprises mixing(a) aqueous dispersions or colloidal aqueous solutions with at least one amphiphilic polymer, and(b) an aqueous solution of a polycarboxylatein a weight ratio of (a):(b) of from 1:1 to 1:20, each based on the solids, or dispersing at least one amphiphilic polymer in an aqueous solution of a polycarboxylate, and spray-drying the dispersions thus obtainable to form finely divided polymer mixtures, use of the finely divided polymer mixtures as ingredient of detergent and as laundry aftertreatment, and finely divided polymer mixtures having a particle size from 20 .mu.m to 3 mm prepared by the above-indicated process.
