Modified Alicyclic Epoxy Resins

In the field of high-performance materials, epoxy resins have gained significant attention due to their excellent mechanical properties, electrical insulation, and chemical stability. traditional alicyclic epoxy resins exhibit limitations such as poor heat resistance and insufficient moisture resistance. To overcome these drawbacks, researchers have conducted modification studies on alicyclic epoxy resins to achieve superior performance. This paper explores the research progress and application prospects of modified alicyclic epoxy resins.

I. Basic Principles of Modified Alicyclic Epoxy Resins

Alicyclic epoxy resins are high-molecular-weight compounds formed through ring-opening polymerization reactions between alicyclic compounds and epoxy groups.
