Olefin metathesis polymerization has been extensively explored for the synthesis of various degradable polymers. Cyclic-acyclic monomers metathesis polymerization (CAMMP) has recently been reported to produce degradable polymers via copolymerization of cyclic monomers with acyclic diene comonomers. Unfortunately, this strategy suffers from poor product material properties, especially at high contents of diene comonomers. To address this issue, a tandem olefin metathesis polymerization (TOMP) system has been designed that combines olefin ring-closing metathesis (RCM) of diene comonomers followed by ring-opening metathesis copolymerization (ROMCP) with cyclic olefin monomers (dicyclopentadiene, cyclooctene, or alkyl-substituted cyclooctene). This strategy overcomes the intrinsic limitations of diene-induced chain-transfer reactions during olefin metathesis, leading to degradable polymers with high molecular weights and excellent material properties. The selection of different cyclic olefin monomers provided access to degradable and recyclable cross-linked thermosets, linear thermoplastics, and elastomers. Notably, this one-pot, two-step process is highly efficient and requires the addition of only one metathesis catalyst.
