摘要： Disclosed herein is an improved pitch for making readily stabilizable, substantially nonmesophasic carbon fibers. The pitch has a softening point of about 250.degree. C. (480.degree. F.) or above and is produced from an unoxidized thermal petroleum pitch by selectively reducing or eliminating a portion of the low molecular weight materials in a very short period of time so that the tendency to produce mesophase pitch is eliminated or reduced and so that the chemical integrity of the components of the higher molecular weight fractions is preserved as much as possible. Also disclosed is a method of producing carbon fibers therefrom and rovings or mats from such fibers.

C. The pitch contains about 12-20 mole % of molecules having an average molecular weight of less than about 600, about 55-70 mole % of molecules having an average molecular weight of from about 600-1,500 and about 20-30 mole % of molecules having an average molecular weight of higher than about 1,500. Fibers melt spun from this mesophase pitch can be converted to carbon or graphite fibers having high strength and modulus of elasticity by a heat treatment which consists of heating to a temperature of 200.degree.-350.degree. C. in an air atmosphere, then heating to about 1,000.degree. C. or higher in an inert gas atmosphere. Such mesophase pitch is produced by polymerizing a naphthalene derivative having at least one methyl group for about 5-300 minutes at a temperature of about 180.degree.-400.degree. C. and at a pressure of about 5-100 atmosphere in the presence of about 0.1-20 moles of HF and about 0.05-1.0 mole of BF.sub.3 per mole of the naphthalene derivative.
