Title:
METHOD FOR PRODUCING PETROLEUM RESIN FOR HOT-MELT ADHESIVE, AND METHOD FOR PRODUCING HYDROGENATED PETROLEUM RESIN
Document Type and Number:
WIPO Patent Application WO/2021/200802
Kind Code:
A1
Abstract:
Provided is a method for producing a petroleum resin using a tube-type reactor, the method producing a petroleum resin that exhibits good properties as an adhesive component for a hot-melt adhesive which has a narrow molecular weight distribution and a high softening point, and which exhibits good adhesive capability and also has little insoluble matter. A method for producing a petroleum resin using a raw material containing at least a cyclopentadiene-based component (A) and a styrene-indene-based aromatic component (B), by thermal polymerization of the raw material, the method being characterized by having a first polymerization reaction step for thermally polymerizing the raw material using a loop reactor, and a second polymerization reaction step for thermally polymerizing the polymerization product obtained in the first polymerization reaction step using a plug flow reactor.
