Abstract:
We investigated the use of crude chlorophyll extracts to catalyze photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under red light irradiation. We discovered that Chl a degrades under visible light in the presence of air, which can eliminate the need for catalyst removal after polymerization.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
