Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, U.S. Gov’t, Non-P.H.S., Research Support, Non-U.S. Gov’t, Journal of the American Chemical Society called Depolymerization of Hydroxylated Polymers via Light-Driven C-C Bond Cleavage, Author is Nguyen, Suong T.; McLoughlin, Elizabeth A.; Cox, James H.; Fors, Brett P.; Knowles, Robert R., which mentions a compound: 17696-11-6, SMILESS is O=C(O)CCCCCCCBr, Molecular C8H15BrO2, SDS of cas: 17696-11-6.
The accumulation of persistent plastic waste in the environment is widely recognized as an ecol. crisis. New chem. technologies are necessary both to recycle existing plastic waste streams into high-value chem. feedstocks and to develop next-generation materials that are degradable by design. Here, we report a catalytic methodol. for the depolymerization of a com. phenoxy resin and high mol. weight hydroxylated polyolefin derivatives upon visible light irradiation near ambient temperature Proton-coupled electron transfer (PCET) activation of hydroxyl groups periodically spaced along the polymer backbone furnishes reactive alkoxy radicals that promote chain fragmentation through C-C bond β-scission. The depolymerization produces well-defined and isolable product mixtures that are readily diversified to polycondensation monomers. In addition to controlling depolymerization, the hydroxyl group modulates the thermomech. properties of these polyolefin derivatives, yielding materials with diverse properties. These results demonstrate a new approach to polymer recycling based on light-driven C-C bond cleavage that has the potential to establish new links within a circular polymer economy and influence the development of new degradable-by-design polyolefin materials.
The article 《Depolymerization of Hydroxylated Polymers via Light-Driven C-C Bond Cleavage》 also mentions many details about this compound(17696-11-6)SDS of cas: 17696-11-6, you can pay attention to it, because details determine success or failure
