Plastics are inarguably inseparable from our daily life, one of the few ways to get rid of end-of-life plastics that are polluting nature is to produce them such that it is easy to recycle them. One such way is to build monomers with degradable bonds that are responsive to certain chemical stimuli so that the feedstock can be recovered. In this approach, functional groups such as imine[1], ester[2], carbonate[3], ketal[4], and acetal[5] were well explored. Our group previously studied several rigid spirocyclic monomers and their polymers with enhanced thermal properties, particularly glass-transition temperatures.[5] The rigidity of the spirocyclic structure is responsible for enhanced thermal properties, this poster presentation discuss some of these monomers and thermal, degradation properties of their polyesters.
