9 Claims

1. A method for producing a dicyclopentadiene-based resin, the method comprising:

a) a primary thermal polymerization step of thermally polymerizing a monomer composition in a continuous stirred tank reactor (CSTR) under non-catalytic conditions, the monomer composition containing a mixed monomer of dicyclopentadiene and a C₂-C₂₀olefin-based monomer, or a mixed monomer of dicyclopentadiene, a C₂-C₂₀olefin-based monomer, and an aromatic vinyl-based monomer; and

b) a secondary thermal polymerization step of thermally polymerizing a reaction product obtained by the primary thermal polymerization in a plug flow reactor (PFR) under non-catalytic conditions.
