Abstract

Abstract The reaction of polyureas, prepared from the conventional diisocyanates and the α,ω-diaminopolyoxyalkylenes, with pyromellitic dianhydride in N-methyl-2-pyrolidone (NMP) at 165 °C leads to the formation of polyimide elastomers. The polyimide elastomers exhibited excellent physical properties.
