Abstract

We have synthesized 41naphthyl124triazolidine35dione 4NTD in high yield and purity from 1naphthyl isocyanate and used it as a new monomer for polymer synthesis A series of novel naphthalenecontaining polyureas have been successfully prepared from 4NTD with hexamethylene diisocyanate HMDI isophorone diisocyanate IPDI and toluene24diisocyanate TDI in NNdimethylacetamide DMAc or Nmethylpyrrolidone NMP solution in the presence of pyridine triethylamine or dibutyltin dilurate as catalysts Some physical properties and structural characterization of these novel polyureas are reported Fluorimetric studies of the new monomer model compound as well as polymers were also investigated
