Abstract

A method for modifying a polymer carrier material for use as a stationary phase in an analytical or preparative separating method, the method comprising the steps of: providing a polymer carrier material, which is at least partly formed of aromatic hydrocarbon compounds comprising at least two vinyl or allyl substituents; producing hydroxy groups on/in the polymer carrier material by a method comprising an oxidative treatment of the polymer carrier material and a subsequent reductive or hydrolytic treatment of the reaction product; reacting the product from the previous step with a polyfunctional compound. The invention also relates to a polymer carrier material for use as a stationary phase in an analytical or preparative separating method, in particular a chromatography method, produced according to a method according to the invention.
