Synthesis and characterization of polyhydroxyurethanes prepared from difunctional six-membered ring carbonates

Abstract

New polyhydroxyurethanes (PHUs) were prepared from (5-ethyl-2-oxo-1,3- dioxan-5-yl)methyl phenyl carbonate and (5-ethyl-2-oxo-1,3-dioxan-5-yl)methyl imidazolyl carbonate with ethylenediamine, tetramethylenediamine and hexamethylenediamine. These PHUs were characterized by SEC, DSC, TGA, NMR spectroscopy and IR spectroscopy, and the results were compared to previously reported results of PHUs prepared from phenoxycarbonyl-oxymethyl ethylene carbonate with corresponding diamines. © 2011 Koninklijke Brill NV, Leiden.
