Abstract
The ability of thymine to photodimerize has been exploited to synthesize a reversibly chain‐extendable polymer system. The photopolymerization (>270 nm) of α,ω‐thymine functionalized poly(butyl acrylate) (Thy‐PnBuA‐Thy) oligomers was successfully carried out in the solid film state. These polymers were further successfully depolymerized by using shorter wavelength UV irradiation (<250 nm). These studies demonstrate a novel method to synthesize linear reversibly chain‐extendable polymers based on photodimerization of terminally thymine functionalized oligomers.
