Acyclic Triene Metathesis Polymerization with Chain‐Stoppers: Molecular Weight Control in the Synthesis of Branched Polymers

Abstract: The synthesis of branched macromolecules from renewable resources via olefin metathesis is described. We observed that it is possible to control the molecular weight during the acyclic triene metathesis (ATMET) of a triglyceride by the application of methyl acrylate as a chain stopper for this straightforward one step one pot polymerization. The resulting branched materials were characterized by GPC, NMR as well as ESI‐MS and the combination of these techniques provided valuable insights into the polymer struc… Show more

“…The triglyceride used in this study was prepared from glycerol and methyl 10-undecenoate. 41 However, natural triglycerides have been used, such as high oleic content sunflower oil. The Grubbs second generation catalyst was employed for the ATMET and methyl acrylate was used as a chain stopper.…”

“…Olefin metathesis has also been employed in polymer synthesis, primarily through ring-opening metathesis polymerization (ROMP), [102] acyclic diene metathesis polymerization (ADMET), [103,104] or acyclic triene metathesis polymerization (ATMET) [105] . The Grubbs' ruthenium catalyst has been used for the ADMET polymerization of soybean oil, resulting in a variety of materials from sticky oils to rubbers.…”

“…[144] Wenn Modelltriglyceride oder ölsäu-rereiches Sonnenblumenöl zusammen mit einem Kettenabbruchmittel polymerisiert wurden, wurde die Vernetzung vollständig unterbunden, was zu verzweigten Polymeren führte (Schema 19). [145,146] Wegen der Funktionalität der eingesetzten Monomere wurde diese Methode ATMET (acyclic triene metathesis) benannt. Es war so z.…”
