| Abstract: | This work examines some discrepancies between claimed effects in polymerization of certain metal acetylacetonates. Cupric acetylacetonate inhibits the thermal polymerization of styrene but acts only as a retarder in the sensitized polymerization of styrene and in the thermal polymerization of methyl methacrylate. Aluminium acetylacetonate initiates weakly the polymerization of styrene, but ferric acetylacetonate does not influence the rates of polymerization of the above mentioned monomers. |
