The disposing problem of used rubbers and waste tires have become acute in recent years. In this study, styrene-butadiene rubber(SBR) and waste. tire were. decomposed in pyrolysis process. The depolymerized products were identified by instrumental analysis such as GPC, FT-IR, GC-MSD, and calorimeter. SBR and tire were degraded to olygomer with final temperature and heating rate, the optimum operating condition were 20℃/min and 700℃ . The yields of SBR and tire were about 60∼70%, 50∼60% respectively. As a result of GC-MSD, above 50 organic compounds were analyzed in oil.
