Definitions
- the present invention relates to a method for producing a petroleum resin obtained by performing a copolymerization reaction using a specific bullet-substituted aromatic compound, a hydrogenated petroleum resin obtained by hydrogenating the petroleum resin, a method for producing the same, and a method for producing the same. It relates to a hot-melt adhesive tartar having excellent adhesion and containing a hydrogenated petroleum resin. Background art
- Hot melt adhesives are being used in various fields because of their excellent properties such as high-speed coating properties, fast-curing properties, solvent-free properties, barrier properties, energy savings, and economic efficiency.
- Typical hot melt adhesives include natural rubber, ethylene monoacetate vinyl copolymer, styrene-butadiene-styrene block copolymer and its hydrogenated product, styrene-isoprene-styrene block copolymer and the like.
- a composition in which a tackifier resin or a plasticizer is blended with a base polymer such as a hydrogenated product is used.
- tackifying resin petroleum resins, cumarone resins, phenol resins, terpene resins and rosin resins, and hydrogenated products thereof are generally used.
- Hot melt adhesives mainly consist of three components: tackifying resin, base polymer and plasticizer.
- the properties of the tackifying resin are one of the factors that greatly affect the performance of the hot melt adhesive.
- petroleum resins obtained by conventional production methods may contain high molecular weight substances having an average molecular weight of tens of thousands to hundreds of thousands, and may deteriorate adhesive properties such as adhesive strength and holding power.
- An object of the present invention is to obtain a tackifying resin excellent in adhesive performance such as adhesive strength and holding power under such circumstances. Disclosure of the invention
- the present inventors have conducted intensive studies to achieve the above object, and as a result, the content of a homopolymer having a certain molecular weight or more of a vinyl-substituted aromatic compound in a petroleum resin obtained by a copolymerization reaction is correlated with the adhesive performance.
- the present invention has been found that petroleum resins having a small amount of high molecular weight substances and a narrow molecular weight distribution can be obtained by using a butyl-substituted aromatic compound containing substantially no high molecular weight substances as a raw material. Was completed.
- a method for producing a petroleum resin in which a cyclopentadiene compound and a vinyl-substituted aromatic compound substantially free of a high molecular weight compound are copolymerized in the presence of a solvent is a method for producing a petroleum resin in which a cyclopentadiene compound and a vinyl-substituted aromatic compound substantially free of a high molecular weight compound are copolymerized in the presence of a solvent.
- Examples of the pentagon compound having a mouth in the present invention include pentagen in a mouth, a pentagen in a methinoresin, a pentagen in eth / resin, and dimers and codimers thereof.
- vinyl-substituted aromatic compound examples include styrene, ⁇ -methylstyrene, ⁇ -methynolestyrene, vinyl / retholene, vinylinlexylene, indene, methynolindene, and ethylindene.
- Examples of the polymerization solvent that can be used in the method for producing a petroleum resin by the copolymerization reaction of the present invention include an aromatic solvent, a naphthene solvent, and an aliphatic hydrocarbon solvent.
- a solvent such as benzene, toluene, xylene, hexahedral hexane, dimethinolex hexane, and ethyl hexane can be suitably used.
