Abstract
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.degree. to 400.degree. C.; and a process for preparing the same: ##STR1## wherein X is selected from O and S; and Ar is selected from ##STR2## wherein R.sup.1 and R.sup.2 are each selected from alkyl 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.
