Morphology and Mechanical Behavior of Isomeric Graft Copolymers and Interpenetrating Polymer Networks.

摘要

The major accomplishments encompass four areas of research: (1) Controlled Grafting of Simultaneous Interpenetrating Polymer Networks. This research, which elucidated the relationship between polymer 1/polymer 2 compatibility and deliverately introduced graft sites, has now been accepted for publication by Polymer Science and Engineering. From an engineering point of view, the controlled morphology produced using epoxy/acrylic combinations yielded very tough, novel plastics. (2) Novel Staining Techniques for Saturated Two-Phased Polymers. Up till now, the only good staining technique for polyblends utilized an osmium tetroxide attack on polymer containg double bonds. The research under this contract showed how this method could be successfully extended to carboxyl or ester containing systems such as acrylics or methacrylics. (3) Polymer Blend and Interpenetrating Polymer Network Nomenclature. A major stumbling block in the development of multicomponent polymer systems has been an inadequate nomenclature. (4) The first experiments on decrosslinking of interpenetrating polymer networks was done under the auspices of this contract. Overall, significant progress was achieved in several areas of research. Several papers have either already appeared in print or will do so in the coming months.
