摘要：PCT No. PCT/JP90/01593 Sec. 371 Date Aug. 18, 1992 Sec. 102(e) Date Aug. 18, 1992 PCT Filed Dec. 6, 1990 PCT Pub. No. WO91/12227 PCT Pub. Date Aug. 22, 1991.The present invention provides an aromatic oligomer comprising repeating structural units represented by the following formula (I), which oligomer has a number-average degree of polymerization of 2 to 10 and a flow temperature of 100 DEG to 400 DEG C.; and a process for preparing the same: S; and Ar is selected from <IMAGE> <IMAGE>group having 1 to 3 carbon atoms and phenyl group, and p and q are each an integer of 0 to 2. The aromatic oligomer of this invention is mixed or reacted with a polymeric substance such as thermoplastic resin, thermosetting resin and rubber to realize enhancement of performance and functional characteristics of the polymeric material.
