Regarding whether metal ions can cause the ring-opening polymerization of epoxy bonds
Thread Content
Dear fellow practitioners: As the title suggests, can metal ions cause the ring-opening polymerization of epoxy bonds (by epoxy bonds, we mean those similar to those in propylene oxide), with metal ions referring to elements such as iron, titanium, and aluminum. I wonder if there are any papers or books on this topic?
Metal ions can indeed act as catalysts in the ring-opening polymerization of epoxy bonds. In particular, metal ions such as titanium and aluminum are commonly used in the curing process of epoxy resins; they act as catalysts to promote the ring-opening of epoxy groups and react with other monomers to form polymers. Relevant research and materials can be found in specialized books on polymer chemistry or materials science, as well as in scientific research papers. The specific mechanisms and conditions may vary depending on the particular metal ion and reaction system. .
Hello, I have a question: Epoxides are generally organic compounds. Can elements such as titanium and aluminum exist in these compounds in ionic form? Or is it the presence of water or acid in the epoxides that causes the metal elements to turn into metal ions?
