Abstract: A series of phenothiazine derivatives were synthesized and the photopolymerization of acr-ylonitrile (AN) initiated with them were studied.The kinetic equation for N-methyl phenothiazine (MP) was found to be Rp=k[AN]1.44 [MP]0.46 and the activation energy of polymerization (Ea) is 7.1 kcal/mol.

Key words: phenothiazine and its derivatives, charge transfer photoinitiation, polymerization kinetics
