Abstract
New dialkynyl monomers containing furan and ester or amide units were prepared via three step reactions from ethyl furan-2-carboxylate. Their click polymerization with either poly(ethylene glycol) diazide or poly(tetrahydrofuran) diazide catalyzed by Cu(I) led to corresponding amorphous poly(ester triazole) and poly(amide triazole) with molecular weights in the range of (7-11) 10 super(3) and with glass transition temperatures in the range of -35 and -19 degree C. The temperature at 5% wt loss (T sub(10)), determined from TGA of polyazomethines were in the range 345-365 degree C indicating their good thermal stability.
