Abstract
The present invention relates to a method for producing an isocyanate-based polymeric material by polymerizing a reaction mixture which comprises different reaction components, including at least one polyisocyanate component and at least one component which is reactive towards said polyisocyanate component. The reaction components comprise at least one anchor component which has at least one anchor group which enables to bond a functional component covalently to the polymeric material. The anchor group is a reactive unsaturated group which does not react during the polymerization process so that the polymerization process is not interfered. The anchor group is selected to that it can bind the functional component by a click chemistry reaction to the polymeric material. It is more particularly selected so that it can participate in a catalyzed Huisgen 1,3-dipolar cycloaddition reaction or in a Diels-Alder cycloaddition reaction The invention also relates to the obtained isocyanate-based polymeric material, to the use thereof to produce a functionalized polymeric material and to this functionalized polymeric material.
