PURPOSE:To improve the mechanical properties, and resistance to oxidation, abrasion, and heat by thermally reacting and/or thermally melting a specific random copolymer with an arom. polycyclic compd. CONSTITUTION:100 pts.wt. random copolymer (A) comprising a transition metal-contg. organosilicon polymer and an arom. polycyclic compd. obtd. from a petroleum- or coal-derived pitch thermally treated and eliminated org. solvent soluble components, wherein Si atoms of said organosilicon polymer are bonded at least partially to C atoms on arom. rings of said polycyclic compd. through Si-C linkage, and 5 to 900 pts.wt. arom. polycyclic compd. (B) comprising a mesophase or two phases, i.e., said mesophase and an optically isotropic phase, are thermally reacted and/or thermally melted at 200 to 500 deg.C. Said organosilicon polymer mainly comprises a bonding unit, Si-CH2, or said bonding unit and another bonding unit, Si-Si, contains H, a lower alkyl, phenyl, or silyl group as a side chain attached to Si, and contains at least one metal selected from the group consisting of Ti, Zr, and Hf bonded directly or through an oxygen atom to at least a part of Si atoms in said bonding units in the main polymer chain. Said arom. polycyclic compd. (B) is obtd. by thermally treating org. solvent insoluble components in a thermally treated petroleum- or coal-derived pitch.
