    <description descriptionType="Abstract">&lt;p&gt;Today&amp;#39;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 &amp;quot;one-pot&amp;quot; synthesis for narrow polydispersity bis-end-functional (=homotelechelic) ROMP polymers exploiting the propagating ruthenium complex&amp;#39; 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&amp;#39;s functionality tolerance). Complete pre-functionalisation of the initiator is realised&amp;nbsp;&lt;em&gt;in-situ&lt;/em&gt;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.&amp;nbsp;&lt;sup&gt;1&lt;/sup&gt;H-NMR spectroscopic and MALDI-ToF-MS analysis show highly efficient end group functionalisation.)&amp;nbsp;&lt;/p&gt;</description>
