What is Dynamic Mechanical Properties of Crosslinked Polyurethanes Containing Sodium Tetraphenylborate about?

## Abstract Crosslinked polyurethane elastomers consisting of low‐molecular‐weight polyethylene oxide or polypropylene oxide segments crosslinked with an aromatic triisocyanate have been studied. Networks have been prepared containing different amounts of sodium tetraphenylborate. The effects of temperature and salt concentration on their viscoelastic properties have been investigated by modulus and loss‐tangent measurements. Variations of the storage modulus with salt concentration or network chemical structure are directly correlated with variations in the glass transition temperature. In fact, superposition of the various modulus plots on a reduced temperature scale, __T__‐__T__~__g__~, suggests that there is no dependence on salt concentration or polyether chemical structure.
