- the drying step in this example after the hydrogenation treatment of the cyclic olefin-based rosin composition (A), the rosin composition (B) was converted into the above-described manner using a double tube flash drying method. When the cyclic olefin-based polymer was not solidified and was flash-dried at a temperature, the same result as above was obtained.
