Title: TRI-AROMATIC ETHER LINKED AMINES CURED WITH BISF EPOXY RESIN 

 

Abstract:  The reaction kinetics and structure property relationships of isomeric tri-aromatic ether linked amines based on the structure bis (aminophenoxy) benzene cured with diglycidyl ether of bisphenol F (BisF) are investigated in this study. Reaction kinetics are explored using rheological and calorimetric measurements, while structure property relationships are determined from flexural properties, dynamic mechanical properties (DMTA) and thermogravimetric analysis (TGA).  The isomers had a varied substitution pattern from ortho, meta to para, and had a significant impact on both amine reactivity and properties after cure. All of the observed changes could be explained in terms of inductive and resonance effects dominated by the outer aromatic rings. The mechanical and thermal properties were understood in terms of the variations in short molecular mobility within the network architecture, more specifically the extent to which phenylene rotations or π flips occur and is experimentally validated from the breadth of the subambient γ relaxations.
