The Ring-Forming Parameter For the Network Formation by DGEBA－POP diamine Polymerisation: Introduction of State of Reaction in Diamine Unit

Abstract

A molecular model was constructed for the network formation of RA₄ + RB₂ type polymerisation to be applied for the cure of diglycidyl ether of bisphenol A and polyoxypropylene diamino ether. The ring-forming parameter was introduced to measure the competition between intramolecular and intermolecular reactions, and incorporated into the model to improve classical gelation theory.
