Heck coupling reactions are introduced as a modular, very efficient and highly orthogonal method for polymer-polymer conjugation. Several diblock and triblock copolymers (5200 Da ≤ Mn ≤ 17300 Da, 1.08 ≤ PDI ≤ 1.33) were prepared via Heck coupling reactions of acrylate-terminated and aryliodide-terminated polymers. The coupling reactions were performed using the so-called Jeffery's conditions, which allowed the use of equimolar amounts of reacting polymers and low reaction temperatures. Acrylated poly(ethylene glycol) monomethyl ether (PEG), poly(ε-caprolactone) (PCL) and polymers synthesized via head-to-tail selective acyclic diene metathesis (ADMET) polymerisation have been successfully conjugated with both a PEG and PCL containing an aryliodide moiety. © The Royal Society of Chemistry 2012.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
