It relates to a highly heat resistant thermosetting polyimide resin composition that is cured at a temperature of 150&#xb0; C. or less, and provides a cured product that generates a less amount of decomposed gas even under heating to 250&#xb0; C., and has flexibility and adhesiveness. A two-component thermosetting polyimide resin composition containing a liquid A containing a polyimide (a) having a main chain constituted by a repeating unit having a polyoxyalkylenediamine structure with amino groups on both ends thereof, and a liquid B containing a bismaleimide compound, and a cured product of a thermosetting polyimide resin composition obtained by mixing these two liquids and curing the mixture under heating.

A process for producing adamantane (tricyclodecane&lsqb;3.3.1.1 &rsqb;) by isomerization reaction of tetrahydrodicyclopentadiene (tricyclodecane&lsqb;5.2.1.0 &rsqb;) with a HF.BF catalyst, wherein the reaction is carried out in the presence of at least one metal selected from the group consisting of the group 8 metals, the group 9 metals and the group 10 metals of the periodic table and hydrogen, which process can give an intended adamantane at a high selection rate.
