Abstract
The present invention relates to a hydrocarbon resin production method comprising thermal polymerization under non-catalytic conditions, thereby enabling a narrow molecular weight distribution and the realization of uniform physical properties. Specifically, the present invention relates to a hydrocarbon resin production method and a hydrocarbon resin produced thereby, the method comprising thermal polymerization without a catalyst and an initiator, thereby enabling, by a low polydispersity index, a narrow molecular weight distribution, and thus a hydrocarbon resin having uniform physical properties.
Claims11
A method for producing a hydrocarbon resin, the method comprising:
- a) a step of performing a primary thermal polymerization on a primary polymer of the hydrocarbon resin in a continuous stirred tank reactor (CSTR) under non-catalytic conditions;
- and
- b) a step of performing a secondary thermal polymerization on the primary polymer in a plug flow reactor (PFR) under non-catalytic conditions.
