    摘要: The invention relates to a method for functionalizing a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalize this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalization of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.
