ABSTRACT:
Novel monomeric compounds containing the 2,7-diazaspiro[4.4]-nonane-1,6-dioine ring system are produced by contacting an amine hydrohalide and a 2,7-dioxaspiro[4.4]nonane-1,6-dione. The resulting spirodilactam compounds are characterized by improved hydrolytic and thermal oxidative stability.
