Process for the preparation of a composition comprising hyperbranched compounds

Abstract

A process for the preparation of a composition comprising hyperbranched polymeric compounds, which comprises a step of reacting a mixture comprising one or more compounds of the following formula (I): AR(B)n wherein A and B are functional groups, R is an (n+1)-valent organic group containing one or more thioether groups and n is an integer of at least 2 characterized in that A is an amino group or a hydroxyl group, and B is a carboxylic acid group or an ester or anhydride thereof, under reaction conditions wherein A reacts with B and forms a linking amide group, while A does not react with A and B does not react with B.
