Abstract:: Polyolefins (mainly polyethylene and polypropylene) are one of the most widely used polymers, However, it’s widely used has caused severe environment pollution problems, posing unprecedented challenges to humanity and the Earth’s ecosystem. The synthetic strategies to synthesis polymers by ring-opening metathesis polymerization (ROMP) exhibit various advantages, such as simple synthesis steps, well control of polymer composition, molecular weight and molecular weight dispersity could be achieved by ROMP. Environmentally cleaner and greener degradable polyolefin-like materials can be synthesized by adding polar functional groups. Three types of diene ester monomers were synthesized using diol and undecyloyl chloride as raw materials by Grubbs Ⅱ catalyst, two types of polyolefins, namely thermoplastic and thermosetting, were generated from cyclohexene and dimer cyclopentadiene, and their structures were characterized and performance tests were conducted. The research results indicated that the synthesized polyolefin-like materiasl had good mechanical properties and can be chemically degraded.
