Abstract
SynopsisNovel polymers with dynamic bonds were developed from prepolymers having anthracene groups in side chains and at chain ends. The polymerization of the prepolymer by photodimerization of anthracene group and the depolymerization by photo-/thermal-dissociation of the linkage were followed by UV-vis measurement. As main chains of the prepolymers, polystyrene and poly(ethylene adipate) were selected. Polystyrene is in the glass state at room temperature while poly(ethylene adipate) is in the semicrystalline state. Through the comparison of the polymerization/depolymerization behavior of these polymers, the effect of the molecular mobility on the reaction was discussed.
