RESIN COMPOSITION

摘要

A resin composition useful as a vibration−damping agent or the like, which is produced by adding at least 1 wt% of a styrenated phenol obtained by reacting a phenol with styrene to a polycyclic aromatic oligomer obtained by condensing a polycyclic aromatic compound bearing two or three rings with formaldehyde. The polycyclic aromatic oligomer is one which is obtained by reacting a polycyclic aromatic compound with a formaldehyde and, if necessary, a phenol in the presence of an acid catalyst and has a number−average molecular weight of 300 to 1000, and the styrenated phenol is one prepared by reacting a phenol with 1 to 2.5 times by mole as much styrene as the phenol in the presence of an acid catalyst.
