	Polyurethane-imide elastomers (PUIEs) are formed from isocyanates, polyols,
diamines, and acid anhydrides through liquid polymerization. However,
thermoplastic PUIEs have rarely been reported because the synthesis of thermoplastic
PUIEs remains a challenge in polymer chemistry. In this study,
PUIEs were prepared from 4,4'-diphenylmethane diisocyanate, polyols (polytetramethylene
glycol (Mw = 1000), polycaprolactone diol (Mw = 1000), and
polycarbonate diol (Mw = 1000)), 4,4'-oxydianiline, and acid anhydrides (pyromellitic
dianhydride and 4,4'-oxydiphtaric anhydride). The thermoplasticities
of the resultant PUIEs were investigated, and only PUIEs synthesized using
4,4'-oxydiphtaric anhydride expressed thermoplasticity.
