Polymerization photoinitiated by carbonyl compounds. XI. Styrene polymerization photoinitiated by cyclododecanones

To establish their potential as source of biradicals to initiate free-radical polymerization, 2-methyl- and 2,2,12-trimethylcyclododecanones were photolyzed in the presence of styrene. The initiation efficiency of both ketones is low - 0.03. The molecular weight of the obtained polymer is ca. 25% hi...
