Abstract:

This paper describes the initial characterization and evaluation of a novel acetylene terminated oligomer 4, 4-bis 3-ethynylphenoxy diphenylsulfone ATS. The approach uses a scientific interdisciplinary team concept to generate material properites. The result is an initial characterization of the reactive oligomer ATS and the crosslinked polymer that results from its thermal cure. This quantitative characterization includes the consideration of cure rheometry, cure kinetics, volume change, secant modulus, tensile properities, dynamic shear modulus and surface energetics. From the data generated initial material characteristics have been judged to be of sufficient interest to warrant further material development. Of the properites measured, the polymer is noteworthy in its ease of processing, high temperature 177 degrees C and above mechanical properties, favorable surface properties for moisture resistance, and inherently low moisture pick-up.
