Summary: The study investigates six novel photoacid generators based on anthrone and anthraquinone chromophores capable of producing three different acids upon light irradiation to trigger the ring-opening polymerization of cyclic esters. The efficiency of the catalyst is strongly related to the chromophore and sulfonate substituent. The study confirms their use as effective catalysts for cationic ring-opening polymerization of epsilon-CL in various conditions.

Summary: A main-chain type benzoxazine (MCBZ) resin that can be quickly shaped under UV light was successfully synthesized and directly coated into a film, with wide processing window, low curing temperature, excellent static antifouling effect, and sterilization effect. The d12-DHBP-MCBZ resin was prepared from dodecamine and 4, 4'-dihydroxy-benzophenone. By adjusting the ratio of d12-DHBP-MCBZ to TMPTMA, hydrophilic benzoxazine coatings can be prepared, suitable for fouling-resisting coatings. The coatings exhibited fast shaping under UV light and a post-curing temperature of only 140 degrees C, with excellent hydrophilicity to prevent fouling organisms' adhesion, and a high sterilization performance of >99% for the Poly(BZ/20 %TMA) coating.
