ABSTRACT:
The present invention is directed to C.sub.60 diamine adducts, processes for preparing them and polymers prepared from them. C.sub.60 diamine adducts is a symmetrical icosahegron which is composed of 12 pentagons and 20 hexagons and links to 2 to 4 diamines. The processes for preparing the product comprises the steps of: adding C.sub.60 in benzene or toluene of a constant concentration to a certain amount of linear aliphatic diamine having the structural formula H.sub.2 N--(CH.sub.2)n--NH.sub.2 wherein n=2, 4 or 6 for reaction, or adding a definite amount of C.sub.60 directly to linear diamine of a definite concentration to produce C.sub.60 diamine adducts. Elemental analysis shows that the product contain about 5.9% nitrogen, about 72.6% carbon and about 3.84% hydrogen, and the number of diamine linked to C.sub.60 is in the range of 2 to 4. C.sub.60 diamine is useful as a polymerization monomer for the preparation of polyamides or relevant polymers.
