Graft polymers comprising side chains containing cyclic N-vinylamides

Graft polymer, comprising (A) a polymer graft skeleton with no mono-ethylenic unsaturated units and (B) polymer sidechains formed from co-polymers of two different mono-ethylenic unsaturated monomers (B1) and (B2), each comprising a nitrogen-containing heterocycle, whereby the proportion of the sidechains (B) amounts to more than 55 wt. % of the total polymer.

Detergent and tableware cleaner

Glycine-N,N-diacetic acid derivatives and their alkali metal, alkaline earth metal, ammonium and substituted ammonium salts are used as complexing agents for alkaline earth metal and heavy metal ions with the exception of .alpha.-alanine-N,N-diacetic acid as textile detergent builders in powder detergent formulations and as calcium sequestrants in oral hygiene products.

Use of glycine-N, N-diacetic acid derivatives as biodegradable

Use of glycine-N,N-diacetic acid derivatives as biodegradable complexing

Solid textile detergent formulation comprising inorganic builders,

A crystalline solid which has a sufficiently low hygroscopicity for processing and use and essentially consists of glycine-N,N-diacetic acid derivatives is prepared by adjusting the water content of the starting material containing the glycine-N,N-diacetic acid derivatives to a value of from 10 to 30% by weight, based on the starting material, and subsequently bringing about crystallization.

Use of triacids based on alkoxylated tertiary amines as complexing agents

Glycine-N,N-diacetic acid derivatives I ##STR1## where R is unsubstituted or substituted alkyl, alkenyl, alkoxylate groups, phenylalkyl, phenyl, a heterocyclic ring or a radical of the formula ##STR2## where A is an alkylene bridge or a chemical bond, and M is hydrogen, alkali metal, alkaline earth metal, ammonium or substituted ammonium in the appropriate stoichiometric amounts, are prepared by reacting

Preparation of glycine-N,N-diacetic acid derivatives

Glycine-N, N-diacetic acid derivatives are prepared by reacting corresponding 2-substituted glycines, 2-substituted glycinonitriles, doubled glycines, or precursors of the glycine derivatives with formaldehyde and alkali metal cyanide. The reaction is conducted in an aqueous medium at a pH of 8 to 14. From 0, 5 to 30% of the amount of alkali metal cyanide required for the reaction are added to the glycine derivatives or precursors thereof Subsequently, the remaining amount of alkali metal cyanide and the formaldehyde are simultaneously metered in over a period of from 0.5 to 12 hours.
