| Inhoud: |
It has been proved that lead dithizone and carbazone complex compounds act as adequate initiators and indicators for radical polymerization of methylmethacrylate. The color change observed during the polymerization process was attributed to the change in structure of the complex compounds according to tautomerization mechanism. Improvements to both polydispersity and relative crystallinity were observed in presence of lead dithizone and carbazone complex compounds. Better protection against gamma radiation was noticed ascertained through molecular mass measurements. A convincing reaction mechanism was also given. |
