ABSTRACT:
Novel thermosetting resin compositions comprise a mixture of the epoxyalkylether of a 1,6-diazo[4.4]spirodilactam having a hydroxyaryl substituent on each of the spiro ring nitrogen atoms, and at least one amine compound. The cured compositions obtained by heating the resin compositions to an elevated temperature have relatively high glass transition temperatures and good physical properties.
