Cycloaliphatic Epoxides

Many cycloaliphatic epoxies are products of oxidation of cyclic olefins with peracids, like peracetic. These materials were commercialized over the years for use as active diluents, though later some were withdrawn. One commercial group of resins is obtained from cyclopentadiene:

Another group of cycloaliphatic epoxy resins are prepared via Diels–Alder additions, followed by a Tischenko reaction, and completed by epoxidation. A preparation, for instance, may start with butadiene and acrolein:

Examples of some other cycloaliphatic epoxy resins are:

Acid anhydrides are more effective curing agents for cycloaliphatic epoxy resins than are the amines. In addition, the amines might also react with ester groups that are present in some of these materials and form undesirable by-products.
