A series of new eco-friendly photoinitiating systems (PIs) based on several water-soluble xanthenic dye/PAMAM dendrimer formulations are tested by polymerizing a typical vinyl monomer such as acrylamide. After irradiation with visible LEDs, solutions of viscosity up to 15-fold higher than those with PIs based on low mol. weight amines are obtained. A correlation between solution viscosity and dendrimer structure is also observed Polymers with ultra-high mol. weights up to around 107 are estimated from viscosimetric assays. In addition, very fast reactions are observed under direct solar radiation and the properties of the thus obtained polymers are similar to those synthesized with LEDs. The present findings are promissory for future research and technol. applications of the PIs evaluated. In the experiment, the researchers used many compounds, for example, Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0Product Details of 16423-68-0).
Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Product Details of 16423-68-0
