linked / cross-linked Explanation: The syntaxt of the sentence appears to indicate that the polyesters are linked to the other groups. I read "verschlossen" here as angeschlossen. "closed-end" cannot be found in connection with polyesters in the chemical litertaure. Composite Materials (References) ...

end-capped Explanation: the reactive groups at either end of the polymer chain are made inert by end-capping. The polymer cannot grow any more.

These can be cross-linked (= Quervernetzung). Another name for this is curing (Aushärten).
