Abstract: An Aramid‐CTBN block copolymer was added to a Bisphenol‐A type epoxy resins modified with CTBN. With the addition of the copolymer, the impact strength of the CTBN‐modified systems was about twelve times higher than that of the unmodified system. Transmission electron micrographs of the block copolymer‐epoxy system showed that the diameter of CTBN‐dispersed phase decreased and a number of fine CTBN phases were dispersed in the matrix. The deformability of matrix in these systems increased with a dispersion of the fine CTBN phase. It is concluded that the improvement of toughness of the cured resins is due to the increases in the ductility of epoxy matrix by the incorporating of the dispersion of the fine CTBN phase in the matrix.
