Abstract
The photoinitiation efficiency of the free-radical polymerization of
methyl methacrylate and styrene by several carbonly compounds has been
determined. The compounds considered were -substituted ketones and
-dicarbonyl compounds. For the ketones, the initiation efficiency
employing methyl methacrylate depends on the substitution; the values
obtained change from less than 10-3 (acetone) to 0.65
(3-hydroxy-3-methyl-2-butanone). All ketones are more efficient towards
methyl methacrylate than styrene. This result can be explained in terms
of triplet quenching by the last monomer. The results obtained employing
-dicarbonyl compounds do not conform to a simple pattern. In particular,
benzil shows a considerably larger efficiency towards styrene than for
methyl methacrylate. Since benzil is efficiently quenched by styrene,
the initiation must involve the interaction of an excited benzil
molecule and the monomer.
