ACS omega, 2020•ACS PublicationsAcyclic 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 (H2 1.0 MPa, 50° C, 3 h) gave the saturated polymers
upon addition of a small amount of Al2O3 (1.0–1.7 wt%). Subsequent reaction of the

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 (H2 1.0 MPa, 50 °C, 3 h) gave the saturated polymers upon addition of a small amount of Al2O3 (1.0–1.7 wt %). Subsequent reaction of the unsaturated polymers with ethylene afforded the oligomers (by depolymerization and degradation).
