実験手順
Proportions of phenolic-modified rosin (from Example 1) and dicyclopentadiene, as indicated in Table II, were charged into a one-liter autoclave reactor. The charged autoclave was purged with nitrogen and sealed. The reaction mixture was heated to 260° C. within 60 minutes and maintained at 260° C. for six hours. The reactor then was vented carefully, and the molten resin poured into an aluminum pan and allowed to cool.
