Abstract
A process is disclosed for preparing di- or oligoamide alkoxylates. Diamides are prepared from carboxylic acids or carboxylic acid alkyl esters and di-, oligo-, or polyamines and are alkoxylated as a melt directly after their preparation, without any further intermediate preparation process.
Claims14
A process for preparing di- or oligo amide alkoxylates characterised in that carboxylic acids or carboxylic acid alkyl esters are reacted with di-, oligo- or polyamines and are alkoxylated as a melt immediate after reaction without any intermediate isolation or treatment to produce compounds according to formula (I):
- wherein R1 and R2, independently of one another, are a hydrocarbon radical with 1 to 22 carbon atoms, R2 is a bridging group, X and Y, independently of one another, are substituents, and n is the degree of oligomerisation of from 1 to about 10.
