Fullerene purification remains a challenge to chemists and to a large extent determines fullerene prices. In 2010, the spectral signatures of C 60 and C 70 were observed by NASA's Spitzer infrared telescope in a cloud of cosmic dust surrounding a star 6500 light years away. [ 5 ]
The American Chemistry Council estimated that global chemical sales in 2014 rose by 3.7% to US$5,389,000,000,000. [3] In 2018, Forty-eight of the companies on the list disclosed chemical profits, which totaled US$110,100,000,000, an increase of 1.3% from 2017. The average profit margin for chemical operations for these companies was 9.6%. [1]
Polyfullerene is a basic polymer of the C 60 monomer group, in which fullerene segments are connected via covalent bonds into a polymeric chain without side or bridging groups. They are called intrinsic polymeric fullerenes, or more often all C 60 polymers. Fullerene can be part of a polymer chain in many different ways.

Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.

Buckminsterfullerene is a truncated icosahedron with 60 vertices, 32 faces (20 hexagons and 12 pentagons where no pentagons share a vertex), and 90 edges (60 edges between 5-membered & 6-membered rings and 30 edges are shared between 6-membered & 6-membered rings), with a carbon atom at the vertices of each polygon and a bond along each polygon ...
