FUNCTIONALITY DETERMINATION OF BINDER PREPOLYMERS.

Abstract

This report is the seventh Quarterly Progress Report discussing research aimed at the development of accurate and reasonably fast test procedures to determine the functionality and functionality distribution of prepolymers of interest to the Air Force. Functionality distribution measurements were carried out on CNR-nitroso terpolymer, lot A001-4D. Based on 80% of recovered polymer, the functionality distribution of this lot is composed of 10% nonfunctional, 10-11% monofunctional 20% difunctional, 17-18% tri- and tetrafunctional and 20-21% pentafunctional prepolymer. Projection of these data to the remaining 20% which could not be desorbed suggest that the remainder has a functionality in excess of 5.0. Functionality was found to be strongly dependent on molecular weight, increasing with increase in molecular weight. (Author)
