Polyurethanes (PUs) constitute a significant part in the consumer items, automotive and construction industries due to high versatility. However, most of them are from fossil fuel resources and not essentially degradable, which causes environmental concerns. Here, we synthesized high and low glass transition temperature (Tg) polymers from a single and renewable dihydrofuran resource. Upon the polymerization, end-groups of the polymers were carefully controlled to use them as PU precursors. Low Tg polymer was synthesized via ring-opening metathesis polymerization (ROMP), with imparting multi-functional end groups. High Tg polymer was synthesized via reversible addition-fragmentation chain-transfer (RAFT) using Lab-synthesized difunctional chain transfer agent (CTA). Synthesis of PU by the combination of high and low Tg polymers are in progress and the resultant PU is expected to degrade under a certainly designed condition.
