The present invention relates to acylated polymeric polyamines, to processes for their preparation, to their use, and to aqueous compositions which comprise these polyamines.

Acylated polymeric polyamines

The invention relates to polyalkene alcohol polyetheramines of formula R &mdash;(CH ) &mdash;O&mdash;A) &mdash;NR R , wherein R represents a polyalkene radical derived from C - to C -alkenes with a number average molecular weight of 300 to 5000, R and R each mean, independently of each other, hydrogen or organic radicals with a total of 400 carbon atoms. A denotes alkylene groups with 2 to 8 C atoms, m is a number from 1 to 200 and n denotes the number 0 or 1. The inventive polyalkene alcohol polyetheramines are suitable for use as carrier oils, detergents and dispersing agents in fuel and lubricant compositions.
