Abstract:

The overall objective of this proposal is to develop and study for transition new low viscosity thermoset additives - hyperbranched polymers HBPs - for use in composites needed for emerging space-based Air Force applications. Specifically, we are studying and developing hyperbranched polymers for use as a new low-viscosity thermosetthermoplastic additives, which have enormouos applications in rigid spacecraft structures. The particular projects included i Modification of high performance thermoplastics by non-reactive hyperbranched poly arylene-ether-ketone-imide PAEKI, ii Manipulation of DOB copolymerization with core monomers and study of induced property modification, iii Measurement of Degree of Branch DOB by model compound studies, and iv Synthesis of hyperbranched liquid crystalline polymer. This program began officially 21 months ago, and during this time we have conducted research with several graduate assistants, but primarily Mr Haihu Qin and Mr. Timothy E. Marsh.
