EFFECT OF SOFT SEGMENT MOLECULAR WEIGHT ON THE MECHANICAL AND STRUCTURAL PROPERTIES OF SILICA FILLED POL YURETHANES

摘要

In this work, we consider the effect of the addition of functionalized silica to a series of poly (tetramethylene oxide) (PTMO) based polyurethanes. We have synthesized urethanes with different molecular weight soft segments (PTMO) and evaluated both structural and mechanical properties. The purpose of this work is to study the potential application of these PTMO based urethane materials as polymer binders for military systems.
