Abstract

A reaction product containing urethane groups, comprising one or more species of the general formula (I)

description='In-line Formulae' end='lead'(R¹—X)_p—Z¹—(XH)_y  (I)description='In-line Formulae' end='tail'

where p+y=w and w is an integer from 2 to 10, p is an integer from 2 to 10, y is an integer from 0 to 8, andX is independently O, NH and/or NZ2 and XH is independently a hydroxyl group OH, a primary amino group NH2 and/or a secondary amino group NHZ2 whereZ2 is independently a branched or unbranched, saturated or unsaturated organic radical G(U)a where U is independently a hydroxyl group, a primary amino group or a secondary amino group anda is an integer from 0 to 8,where w+a≤10,G is a branched or unbranched, saturated or unsaturated organic radical,the p R1 radicals are independently a radical of the general formula (II)Y—O—CO—NH—R2—NH—CO  (II)in which the p Y radicals are independently a branched or unbranched, saturated or unsaturated organic radical which has 1 to 1000 carbon atoms and does not contain any hydroxyl groups, any primary amino groups or any secondary amino groups, the p R2 radicals are independently a branched or unbranched, saturated or unsaturated organic radical having 6 to 20 carbon atoms, and Z1 is a branched or unbranched, saturated or unsaturated organic radical which contains at least one tertiary nitrogen group and is free of XH groups.
