C60 diamine adducts and preparation and polymers thereof

摘要

The present invention is directed to C60 diamine adducts, processes for preparing them and polymers prepared from them. C60 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 C60 in benzene or toluene of a constant concentration to a certain amount of linear aliphatic diamine having the structural formula H2N-(CH2)n-NH2 wherein n=2, 4 or 6 for reaction, or adding a definite amount of C60 directly to linear diamine of a definite concentration to produce C60 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 C60 is in the range of 2 to 4. C60 diamine is useful as a polymerization monomer for the preparation of polyamides or relevant polymers.
