Rubber elasticity in a highly crosslinked epoxy system

摘要: Abstract This work is a study in the field of viscoelastic and elastic behaviour highly crosslinked systems. It was observed that epoxides with amines have well defined transition rubbery plateau regions. The concepts theory rubber elasticity were applied to Epon 826 (Shell Chemical Company) by four aliphatic (EDA, DETA, TETA, TEPA). From measured values Gehman 10 sec modulus region ‘front factor’ equation for networks calculated. By use equations take into consideration molecular structure resin derived one authors an earlier work, front factors calculated agreement between obtained from experiments ones very good.
