The basic building blocks that make up the polyester backbone are the ethylene and/or propylene terephthalate and polyethylene oxide terephalate units (=monomers). These can be cross-linked (= Quervernetzung). Another name for this is curing (Aushärten). HTH!

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.
