EN

The polymerization process of epoxy resins (bisphenol-A dicyanate) was studied using positron-annihilation lifetime spectroscopy. The polymerization from monomer to polymer through a polymerization reaction was followed by positron-annihilation lifetime spectroscopy measurements. Resins kept at curing temperatures (120, 150, and 200°C) changed form from a powder to a solid through a liquid. The size of the intermolecular spaces of the solid samples increased along with the progress of polymerization.
