Abstract

Abstract: Five photoinitiators of thioxcanthone derivatives:2-methylrthioxanthone (2-MTX):2,4-dimethylthioxanthone(2.4-DMTX); 1,2,4-trimethylthioxanthone (1,2,4-TMTX): 2-methoxcythioxanthone(2-MOTX); 2-pentoxythioxanthone(2-AOTX) mixed with triethlamine were studied by ESR. The dark chemical reaction mechanism was also discussed.

Key words: thioxanthone, photoinitiator, electron spin resonance, dark chemical recation, mechanism
