p-Xylylenediamine was prepared by hydrogenation of terephthalodinitrile; the conditions ensuring high yield of this monomer were found. The influence exerted by the catalyst and solvent on the diamine yield was examined. Single-step polycondensation of p-xylylenediamine with tricyclodecenetetracarboxylic dianhydrides in the presence of catalytic amounts of isonicotinic acid gave a series of new polyimides consisting of aliphatic and aromatic fragments.
