Liquid-glass structural transition in the formation of densely crosslinked epoxyamine networks. Effect of transition on properties of polymers☆

Abstract A solid glassy polymer of three-dimensional structure is formed during isothermal solidification of a resorcinol diglycidyl ester- m -phenylenediamine liquid mixture, i.e. liquid-glass structural transition takes place during solidification. A hypothesis was put forward that the structure of the glassy state of the polymer formed, i.e.
