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.

Abstract: Provided are a method of preparing a dicyclopentadiene-based resin and a dicyclopentadiene-based resin. According to the present invention, provided is a dicyclopentadiene-based resin including an aromatic olefin-based comonomer as a comonomer to have improved quality including high compatibility, a favorable color characteristic, and a low softening point, and also having improved adhesive strength due to a low molecular weight and a narrow molecular weight distribution.

Abstract: A mobile terminal with an antenna apparatus is provided. The mobile terminal in one embodiment includes an antenna radiator disposed at a first end of the mobile terminal; at least one antenna modifying element disposed at a second, opposing end of the mobile terminal; and a coupling unit for fastening the first and second ends and electrically connecting the at least one antenna modifying element with the antenna device when the first and second ends are fastened. In another embodiment, a deformation detector detects at least one deformation of the mobile terminal, an antenna matching unit is electrically connectable to the first antenna radiator; and a controller is coupled to the deformation detector, for controlling an electrical connection between the antenna matching unit and the first antenna radiator when the at least one deformation is detected. The antenna matching unit may include a second antenna radiator.
