it generates a secondary hydroxyl group along the epoxy resin molecule. As the curing reaction progresses, this newly formed hydroxyl group further reacts with another anhydride group within the ...

There are three reactions in classic epoxy-anhydride chemistry. What's important to consider is that anhydrides do not react directly with epoxide groups. The anhydride first seeks out a hydroxyl ...

We wished to design a catalyst that contained two sites, one for binding to a hydroxyl group, and another nearby reactive site, and settled on an aldehyde as the binding site and the 4-amino pyridine ...

What sets them apart is their ability to react with both oxirane (epoxide) and secondary hydroxyl groups present in commercial epoxy resins. Additionally, when an anhydride reacts with an oxirane ...
