| Abstract: | Poly(methylsilylene ethynylene phenylene ethynylene)-co-(tetramethyldisiloxane ethynylene phenylene ethynylene)] was synthesized by polycondensation reaction of m-diethynylbenzene magnesium reagent with 1,3-dichlorotetramethyldisiloxane and dichloromethylsilane. The copolymer was characterized by FT-IR, 1H NMR, differential scanning calorimetry and thermogravi-metric analysis. The results show that the copolymer exhibits good processability and cures at low temperatures. The cured copolymer shows high thermal stability. |
| Keywords: | Silicon-containing arylacetylene resin Siloxane m-Diethynylbenzene Methylsilylene |
