Abstract

We would like to report a simple reaction that produces elastomers at room temperature. We call the reaction acyclic diene metathesis (ADMET) polymerization, and it appears to have wide applicability in synthesis of unsaturated flexible polymers. Equally as important, it appears as if this chemistry can be used in recycling elastomers; thus, common polymers such as polybutadiene and polyisoprene may be recycled by converting them into alpha omega dienes. Acyclic diene metathesis (ADMET) polymerization offers a new opportunity to generate a wide variety of elastic structures using room temperature reaction conditions. It also offers the opportunity to modify existing elastomer structures through trans-metathesis copolymerization reactions. ADMET depolymerization could have tremendous significance if, in fact, the reaction can be applied to the recovery of commercial vulcanized elastomers.
