Thermal polymerization of arylacetylenes: spectroscopic and thermal studies

Abstract

The reaction mechanisms and kinetics of endcapped ethynyl polyethers were studies in the temperature range 150-220C. The results obtained by '³C and 'H NMR, FrTIR, HPLC and DSC indicate reactivity differences and competing reactions. These materials were cured and their thermal properties evaluated.
