In this contribution, we reported the transformation of polydicyclopentadiene (PDCPD) from thermoset into vitrimer. First, two N‐coordinated diboronic diols were successfully synthesized via the reaction of N,N,N‐tri(2‐hydroxyethyl)amine and/or N,N,N“,N”‐tetrakis(2‐hydroxyethyl)ethylene diamine with 4‐(hydroxymethyl) phenylboronic acid and then they were transformed into two N‐coordinated cyclic boronic diacrylates. The latter two dienes carrying electron‐withdrawing substituents were used for the ring opening insertion metathesis copolymerization (ROIMP) of dicyclopentadiene to afford the crosslinked PDCPD. In the crosslinked PDCPD networks, N‐coordinated cyclic boronic bonds were integrated. It was found that the as‐obtained PDCPD networks displayed the excellent reprocessing properties. In the meantime, the fracture toughness was significantly improved. Owing to the inclusion of N‐coordinated cyclic boronic ester bonds, the modified PDCPDs had the thermal stability much superior to plain PDCPD. The results reported in this work demonstrated that PDCPD can successfully be transformed into the vitrimers via the introduction of N‐coordinated cyclic boronic ester bonds.This article is protected by copyright.

The tri-block copolymer is used as a carrier to simultaneously immobilize the N-heterocyclic and benzylidene ligands precursor of the Ru-based catalyst to form a dual-site immobilized catalyst. The dual-site immobilized catalyst can catalyze ring-opening metathesis polymerization, ring-closing metathesis and self-metathesis. The dual-site immobilized catalyst shows good heterogeneity in dichloromethane, which simplifies the purification of product and recovery of catalyst. The dual-site immobilized catalyst exhibits excellent activity and recycling performance. The excellent recyclability can be attributed to the capture of ruthenium by the excess ligands precursor on carrier. Importantly, ruthenium residues are not detected in product.
