Abstract: Silicon-containing arylacetylene (PSA) resin was prepared by the condensation reaction between diethynylbenzene and dimethyldichlorosilane catalyzed by zinc powder. The structures of PSA resin were characterized. The optimum reaction conditions were obtained as follows: acetonitrile as solvent, amount of zinc overdosed 200%, temperature 80℃ and reaction time 10 h. And the resulting reaction yield reached up to 82%. The curing behavior of PSA resin was analyzed by DSC, and the thermal stability of cured resin by TGA. The results showed that the PSA resin was easily processed and could be cured at the temperature of about 170℃. The cured PSA resin possessed excellent thermal stability. The temperature at 5% weight loss reached 529℃, and char yield of the cured resin at 800℃ under nitrogen was 85%.

Key words: PSA resin, zinc powder, catalysis, heat-resistant resin
