Abstract
We report that differences in ring strain enthalpy between cis and trans isomers of sila-cycloheptene
provide a driving force for both polymerization and depolymerization via olefin metathesis. A need for
new methods to reintroduce the low-strain isomer into the plastic economy inspired the development of
a polymerization based on ring-opening/cross-metathesis step polymerization, which afforded perfect
sequence control for an alternating copolymer. The chemical principles are a platform for achieving both
efficient polymerization and depolymerization with high mass recovery in functional polymers.
