Abstract
Provided are a resin composition for a tackifier or an adhesive and a preparation method thereof. Provided is a resin composition for a tackifier or an adhesive, which includes a hydrogenated petroleum resin with a controlled hydrogenation rate to have excellent compatibility with polyolefin and to exhibit high transparency while having improved quality including adhesive property.
Claims8
A resin composition for a tackifier or an adhesive, the resin composition comprising:
- a hydrogenated petroleum resin obtained by performing thermal polymerization and hydrogenation of a monomer composition including dicyclopentadiene and C9 monomer;
- and
- a metallocene polyolefin,
- wherein the metallocene polyolefin is a polyethylene (PE)-based polyolefin,
- wherein the hydrogenated petroleum resin includes the C9 monomer in an amount of 5 to 40 wt %, based on the total weight of the dicyclopentadiene and the C9 monomer, and the metallocene polyolefin is a metallocene polyethylene (PE)-based polyolefin,
- wherein the hydrogenated petroleum resin has a hydrogenation rate of 90% to 100%, as measured by the following Equation 1:
- Hydrogenation rate (%)=Number of moles of saturated aliphatic single bonds from aromatic double bonds in hydrogenated petroleum resin after hydrogenation/Number of moles of total aromatic double bonds in petroleum resin before hydrogenation*100. [Equation 1]

A method of preparing a resin composition for a tackifier or an adhesive, the method comprising the steps of:
- preparing a polymerized petroleum resin by performing thermal polymerization of a monomer composition including dicyclopentadiene and C9 monomer;
- preparing a hydrogenated petroleum resin having a hydrogenation rate of 90% to 100%, as measured by the following Equation 1, by performing hydrogenation of the polymerized petroleum resin;
- and
- mixing the hydrogenated petroleum resin and a metallocene polyolefin,
- wherein the metallocene polyolefin is a polyethylene (PE)-based polyolefin,
- wherein the hydrogenated petroleum resin includes the C9 monomer in an amount of 5 to 40 wt %, based on the total weight of the dicyclopentadiene and the C9 monomer, and the metallocene polyolefin is a metallocene polyethylene (PE)-based polyolefin:
- Hydrogenation rate (%)=Number of moles of saturated aliphatic single bonds from aromatic double bonds in hydrogenated petroleum resin after hydrogenation/Number of moles of total aromatic double bonds in petroleum resin before hydrogenation*100. [Equation 1]
