摘要：

1,4-,4,9-, and 1,6-diethynyldiamantanes (3a-c) were prepared from diamantane and polymerized at 250-275-degrees-C to give clear thermoset resins that showed onsets of degradation between 518 and 525-degrees-C in air or helium (TGA). Nickel(II) acetylacetonate or tetrakis(triphenylphosphine)palladium catalysts lowered the polymerization temperature to 210-degrees-C. A copolymer prepared from a mixture of 3a (35%), 3b (58%), and 3c (7%) exhibited onset of major degradation at 476-degrees-C in air.
