Abstract: The present disclosure relates to a UV- and heat-curable ladder-like polysilsesquioxane copolymer and a method for preparing the same. Since a controlled functionality can be provided only on a desired region via a thiol-ene click reaction without an additional additive, an insulating layer having a low dielectric constant and a microcircuit pattern can be formed without an additional etching process.
