Abstract : This work is a study in the field of viscoelastic and elastic behavior of highly crosslinked systems. It was observed that epoxide crosslinked with amines have well defined transition and rubbery plateau regions. The concepts of the theory of rubber elasticity were applied to epon 826 (shell chemical company) crosslinked by four aliphatic amines (EDA, DETA, TETA, TEPA). From the measured values of the gehman 10 sec modulus in the rubbery region the 'front factor' in the equation for rubbery networks was calculated. (Author-PL).
