Abstract

A hydrogenated petroleum resin, and a manufacturing method and use thereof, are provided. More specifically, a hydrogenated petroleum resin manufactured by subjecting dicyclopentadiene and an olefinic monomer to thermal polymerization and then carrying out a hydrogenation reaction, and a manufacturing method and use therefor are provided. The hydrogenated petroleum resin has the advantage of being useful in practical applications, since the petroleum resin is manufactured via thermal polymerization using inexpensive raw materials and on the contrary to conventional catalytic polymerization, a catalyst elimination process can be excluded. The hydrogenated petroleum resin produced in this way can be applied to, for example, an adhesive agent used in environmentally friendly sanitary goods, because the petroleum resin has excellent compatibility, adhesiveness and heat resistance, and has no bad odor.

First claim

What is claimed is:

1. A method for manufacturing a hydrogenated petroleum resin comprising the following steps of:
thermally polymerizing dicyclopentadiene and a C3 to C20 olefinic monomer to prepare a petroleum resin; and
subjecting the petroleum resin to a hydrogenation reaction with a hydrogenation catalyst,
wherein the hydrogenated petroleum resin containing repeating units represented by the following Chemical Formulas 1 and 2:

wherein, R 1 is H or a methyl group, R 2 is a C1 to C18 alkyl group, and 0≤m≤10 and 0≤n≤10, the hydrogenated petroleum resin contains the repeating unit of Chemical Formula 1 of 60 mol % to 90 mol % and the repeating unit of Chemical Formula 2 of 10 mol % to 40 mol %.

2. The method for manufacturing a hydrogenated petroleum resin of claim 1 , wherein the olefinic monomer is a linear or branched alpha olefinic monomer.

3. The method for manufacturing a hydrogenated petroleum resin of claim 2 , wherein the linear alpha olefinic monomer is one selected from the group consisting of propene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-decene, 1-undecene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1-eicosene and a combination thereof.

4. The method for manufacturing a hydrogenated petroleum resin of claim 2 , wherein the branched alpha olefinic monomer is one selected from the group consisting of isobutylene, 3-methyl-1-butene, 2-methyl-1-butene, 3-methyl-1-butene, 4-methyl-1-butene, 3-methyl-1-pentene, 4-methyl-1-pentene, 4-methyl-1-hexene, 5-methyl-1-hexene, 3,3-dimethyl-1-pentene, 3,4-dimethyl-1-pentene, 4,4-dimethyl-1-pentene and a combination thereof.

5. The method for manufacturing a hydrogenated petroleum resin of claim 1 , wherein the thermal polymerization reaction is conducted at 200° C. to 320° C.

6. The method for manufacturing a hydrogenated petroleum resin of claim 1 , wherein the hydrogenation reaction is conducted at a temperature of 150° C. to 300° C. under a pressure of 50 bar to 150 bar.
