A facile route to hyperbranched polymers via acyclic diene metathesis is reported. Any molecule functionalized with two or more acrylate groups and one terminal olefin can serve as an AB_n monomer when exposed to an imidazolinylidene-based ruthenium olefin metathesis catalyst, due to the cross metathesis selectivity of this catalyst. For the polymers obtained by this method, both ^1H NMR spectroscopy and triple detector size exclusion chromatography conclusively indicate a branched architecture.
