Abstract (en)
[origin: EP0026647A1] There is disclosed a mesophase pitch containing at least about 70% by weight mesophase produced by physical operations without chemical operations on a carbonaceous precursor pitch. The mesophase pitch features a molecular weight distribution wherein at least 75% of the molecules have a molecular weight in the range of from about 600 to about 1300; less than about 10% of the molecules have a molecular weight less than about 600; and less than about 15% of the molecules have a molecular weight more than about 1300. There are also disclosed processes for the production of such a mesophase pitch. The mesophase pitch is useful in producing carbon filter and fibers produced from the pitch of the invention are also disclosed.
