High molar absorptivity at 347 nm (1910 L center dot mol -1 center dot cm -1) and good solubility in distilled water (10-2 M) allows WSMPM to be used as an effective photoinitiator also in water-soluble systems. Photopolymerization of acrylamide monomer with WSMPM (10-3 M) and a tertiary amine (N-methyldiethanolamine), resulted in 84.4% monomer to polymer conversion. Based on laser photolysis and electron spin resonance, a photoinitiator mechanism was proposed.eninfo:eu-repo/semantics/openAccessphotopolymerizationwater-soluble photoinitiatorsquaternary ammonium saltArticle10.14314/polimery.2023.4.3684215220WOS:0011556273000012-s2.0-85167871000Q4Q3
