Title:

HYDROGENATED AROMATIC OLIGOMERS AND PROCESS FOR THEIR PRODUCTION

Document Type and Number:

WIPO Patent Application WO/2002/006365

Kind Code:

A1

Abstract:

Hydrogenated aromatic oligomers represented by the general formula (1): (A - F)¿n? - A (wherein A is a component which mainly comprises a polycyclic aromatic compound, a phenol, or a product of hydrogenation thereof and at least a part of which is constituted of the product of hydrogenation; F is methylene or dimethylene ether; and n is a number of 1 to 100). The oligomers are each prepared by reacting a polycyclic aromatic compound such as naphthalene with formaldehyde or a like compound and a phenol in the presence of an acid catalyst and then hydrogenating the obtained product. The oligomers are odorless, excellent in transparency, and useful in improving resins or rubbers in tackiness and damping properties, and exhibit excellent performances suitable for dampers particularly over a wide temperature range.
