Abstract
In this paper the macroscopic properties of the tetrafunctional epoxy resin (N,N'-tetraglycidyl ether of diaminodiphenylmethane) cured by 4, 4'-diaminodiphenylmethane, were studied. For the system the influence of various curing conditions on the glass temperature was investigated . Results obtained for two compositions: an unmodified one and a modif ied with coal were compared with information on the free volume given by the positron annihilation technique.
