【Abstract】 DSC and FTIR were used to characterize the curing kinetics and the structure changes of polyarylacetylene. The results indicate that cis conjugated polyene structures are formed predominantly during the curing of arylacetylene polymer. Monomer structure has a significant influence on the curing reaction rate of the polymer. Poly ( p DEB) has a lower maximum reaction temperature and curing reaction activation energy than that of poly ( m DEB) because of their different structures. This indicates that Poly ( p DEB) has a higher curing reaction rate than that of poly ( m DEB). The curing reaction activation energies of the three kinds of polymers are in the range of 108.6～119.7kJ/mol.更多还原
