The present invention relates to an intermediate for preparing porous silicon oxycarbide, a method of preparing the same, and a lithium secondary battery including porous silicon oxycarbide prepared from the same as a negative electrode active material. According to the present invention, since an intermediate prepared by adding a polyhedral oligomeric silsesquioxane (POSS) to a reaction mixture for preparing silicon oxycarbide, which is composed of a polysiloxane polymer and an aromatic compound, is pyrolyzed to prepare porous silicon oxycarbide (SiOC), although the content of a free carbon region is lower compared to conventional silicon oxycarbide, the cage structure of the POSS is maintained in the pyrolysis to form many pores uniformly distributed in the SiOC matrix, and thus rapid diffusion of electrolyte ions is possible, and because the contents of SiO.sub.3C and SiO.sub.2C.sub.2 in the SiOC matrix are increased, a reversible capacity in the Si—O—C phase can be enhanced.

A siloxane polymer contains a silsesquioxane unit and a linear siloxane unit in its main chain and has a cage-type silsesquioxane structure in its side chain. A highly transparent and flexible film having a small linear thermal expansion coefficient is produced by utilizing the cohesion force (physical crosslinking) of the cage-type silsesquioxane in the side chain. The siloxane polymer has repeating units respectively represented by formulae (1) and (4), and has terminal groups respectively represented by formulae (5L) and (5R) at its right and left terminals, wherein A represents a structure shown below.

A silicone pressure sensitive adhesive composition is curable to form a silicone pressure sensitive adhesive. The silicone pressure sensitive adhesive composition can be coated on a substrate and cured to form a protective film. The protective film can be adhered to an anti-fingerprint coating on display glass, such as cover glass for a smartphone.
