The pollution of plastic has laid a big chemical burden on our environment and has aroused serious attention to sustainable development. The development of degradable polymers is an effective strategy to address the plastic pollution caused by the accumulation of synthetic polymers post-consumer-waste (PCW) plastics. Compared with chemically stimulated degradation, photolabile polymers can degrade into small molecules under light stimuli without treated with organic solvents and other special chemical reagents which may cause additional environmental issues. o-Nitrobenzyl (o-NB) alcohol derivatives, as a kind of efficient photolabile compounds, can photocleave to form o-nitrosobenzaldehyde under UV irradiation (300 nm ~ 365 nm)1. Although a series of photolabile polymers containing o-NB units have been developed and investigated, most of them are prepared via step-growth by using o-NB containing diols as monomers. Ring-opening metathesis polymerization (ROMP) as a powerful chain-growth tool is widely used to prepare functional polymers for different applications2. Herein, we developed a new kind of o-NB containing cyclic olefin as ROMP-type monomer. The monomer can be homopolymerized or copolymerized with other commercially available cyclic olefins such as dicyclopentadiene or norbornene to form photodegradable ROMP polymers. These polymers are expected to exhibit similar mechanical and chemical stability as the original polynorbornene and polydicyclopentadiene, while they also have photodegradable properties due to the introduction of the photolabile o-NB unit. This contribution affords a useful strategy to develop photodegradable polymers and address the environmental issue of plastic pollution.
