AB  - Azoisobutylnitrile (AIBN) initiator was used in the treatment of most widely used 
      domestic plastics in lieu of catalysts. The pyrolysis of low-density polyethylene 
      (LDPE), high-density polyethylene (HDPE), polypropylene (PP), poly-ethylene 
      terephthalate (PET) and polystyrene (PS) plastics with azoisobutylnitrile was 
      carried out individually under nitrogen atmosphere. A series of single 
      (plastic/AIBN) and binary (mixed plastics/AIBN) reactions were carried out in a 
      25-cm(3) micro-autoclave reactor. The optimum conditions selected for this study 
      were: 5% AIBN by weight of total plastics, 60 min, 650 psi and 420 degrees C. It 
      was found that HDPE, LDPE, PP underwent to a maximum cracking and produced 
      highest amounts of liquid and gaseous products. Pyrolysis of PET and PS plastics 
      with AIBN afforded comparatively significant amount of insoluble organic 
      materials. In other reactions, fixed ratios of mixed plastics were pyrolyzed with 
      AIBN that afforded excellent yields of liquid hydrocarbons. This result shows a 
      very significant increase in the liquid portions of the products on using AIBN in 
      the pyrolysis of plastics. The use of AIBN in the pyrolysis of plastics is seems 
      to be feasible and an environmental friendly alternative to catalytic process for 
      maximizing the liquid fuels or chemical feed stocks in higher amounts.
