Abstract
- Acyclic diene metathesis (ADMET) polymerization of biobased α,ω-dienes of bis(undec-10-enoate) with diols (1,4-butanediol, isosorbide, isomannide, and 1,4-cyclohexanedimethanol) afforded high-molecular weight unsaturated polyesters, and subsequent tandem hydrogenation (H <subscript>2</subscript> 1.0 MPa, 50 °C, 3 h) gave the saturated polymers upon addition of a small amount of Al <subscript>2</subscript> O <subscript>3</subscript> (1.0-1.7 wt %). Subsequent reaction of the unsaturated polymers with ethylene afforded the oligomers (by depolymerization and degradation).<br />Competing Interests: The authors declare no competing financial interest.<br /> (Copyright © 2020 American Chemical Society.)
