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.

A method of rapidly forming an elastomer with tunable properties is described herein. The method includes preparing a monomer solution comprising a catalyst and one or more monomers including 1,5-cyclooctadiene (COD). The one or more monomers may further include dicyclopentadiene (DCPD), and each of the COD and the DCPD may be present in the monomer solution at a predetermined volume percentage. A region of the monomer solution is activated to initiate an exothermic polymerization reaction and generate a self-propagating polymerization front, which moves through the monomer solution and polymerizes the one or more monomers. Thus, an elastomer having predetermined properties is rapidly formed.

An optical film, a polarizing plate including the same, and an optical display apparatus including the same are provided. An optical film includes a first layer and a second layer stacked on a lower surface of the first layer via a first primer layer, the first primer layer being formed of a first composition including a first urethane-based polymer and a first isocyanate-based curing agent, the first urethane-based polymer including a repeat unit derived from a first alicyclic isocyanate-based compound, and the first isocyanate-based curing agent including a first isocyanate trimer.
