Abstract
The present disclosure provides compounds of the formula (I): The present disclosure also provides copolymers prepared by polymerizing a first monomer (e.g., dicyclopentadiene) and the compounds. The copolymers may show increased degradability and increased or maintained glass-transition temperature, as compared to homopolymers of the first monomer.
