Abstract
Two kinds of phenylacetylene-terminated poly(silyleneethynylene-4,4′-phenylethereneethynylene)s, {C6H5single bondCtriple bond; length of mdashCsingle bond[Si(R)2single bondCtriple bond; length of mdashCsingle bondC6H4single bondOsingle bondC6H4single bondCtriple bond; length of mdashC]nsingle bondC6H5} wherein R represents methyl or phenyl, were synthesized by condensation reaction between dichlorosilanes and 4,4′-diethynyldiphenyl ether using organomagnesium reagents. The polymers were characterized by NMR, IR, gel permeation chromatography, thermogravimetric analysis, and differential scattering calorimetry.
