Abstract
The invention relates to a method for producing a polymer comprising the following steps: (A) depositing a radically cross-linkable resin, obtaining a radically cross-linked resin; and (B) treating the radically cross-linked resin under conditions which are sufficient to trigger a chemical reaction that is different from the radical cross-linking in the radically cross-linked resin. The radically cross-linkable resin comprises a curable component, in which there are NCO groups, olefinic C═C double bonds and epoxide groups, and the chemical reaction in the radically cross-linked resin that is different from the radical cross-linking is the reaction of NCO groups and epoxide groups to form oxazolidinone groups.
