HCID 866493301,5-Dimethylnaphthalene formaldehyde

Procedure

The experiment was carried out in the same manner as in Example 6, except that in Example 6, 1,5-dimethylnaphthalene obtained in Production Example 2 was used in place of the 2,6-dimethylnaphthalene and that methanol was added, thereby obtaining 100 g of a 1,5-dimethylnaphthalene formaldehyde resin which is a viscous liquid at ordinary temperature. The reaction condition and physical properties of the obtained resin are shown in Table 2.
