{ "description": "<p>Today's olefin metathesis catalysts show high reactivity, selectivity and functional group tolerance and allow the design of new syntheses of precisely functionalised polymers. Here we describe a general "one-pot" synthesis for narrow polydispersity bis-end-functional (=homotelechelic) ROMP polymers exploiting the propagating ruthenium complex' inherent selectivity for strained norbornenes over acyclic internal olefins. This approach represents a straightforward general method of homotelechelic polymers carrying almost any functional end group (within the limitations of the catalyst's functionality tolerance). Complete pre-functionalisation of the initiator is realised <em>in-situ</em>within minutes and without the need of further purification steps. The excess acyclic olefin re-enters the catalytic cycle after monomer consumption is complete giving a homotelechelic polymer. <sup>1</sup>H-NMR spectroscopic and MALDI-ToF-MS analysis show highly efficient end group functionalisation.) </p>", "license": "https://creativecommons.org/licenses/by/3.0/legalcode", "creator": [ { "@type": "Person", "name": "Nils Hanik" }, { "@id": "https://orcid.org/0000-0002-2929-7499", "@type": "Person", "name": "Andreas F.M.
