| The objective of this research was to improve the toughness of epoxy resins without sacrificing their processibility, glass transition temperatures and moduli. This research was divided into two major parts. In the first part, two low-molecular-weight, amine end-capped imide oligomers, which had different reactivities, were dissolved in an epoxy resin. The blends modified with the imide oligomer prepared from 2,2... |
