Abstract: PURPOSE:To prepare the title matrix which does not bring about breakage of a filament, by allowing mesophases in non-mesopitch prepd. from petroleum pitch to fuse and glow into a large size. CONSTITUTION:Petroleum pitch obtained as a by-product of thermal catalytic cracking of a desulfurized vacuum gas oil is distilled in vacuo to obtain a 85%-cut fraction. A fraction ranging from an initial b.p. of 460 deg.C to an end point of 560 deg.C is extracted to separate it into a component (H) extractable with a 6-8C aliph. hydrocarbon and a component (B) extractable with an arom. hydrocarbon. A non-oxidizing gas is blown into component B and, at the same time, heated with stirring at 380-420 deg.C for 2-10hr to prepare pitch containing 5-15% mesophase. The pitch is then heated at 300-350 deg.C for 10-30hr in a non-oxidizing gas stream to allow mesophases to fuse and grow into a large size, and the non-mesopitch constituting the upper layer is separated from the mesophase pitch constituting the lower layer by the difference of specific gravity. The non-mesopitch is heated at 380-420 deg.C for 2-6hr to prepare pitch containing 20-30% mesophase. The pitch thus prepd. is aged at 300-350 deg.C for 10-30hr to allow mesophases to fuse and grow into a large size, followed by separation and recovery thereof.
