Abstract
The present invention relates to a method for producing a dicyclopentadiene-based resin and a dicyclopentadiene-based resin produced thereby, the method comprising thermal polymerizing under non-catalyst, non-initiator conditions, thereby enabling not only excellent yield, but also, by a low polydispersity index, a narrow molecular weight distribution and the realization of uniform physical properties.
Claims9
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-C20 olefin-based monomer, or a mixed monomer of dicyclopentadiene, a C2-C20 olefin-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.
