39. A process for decomposing a polymeric feed composition comprising:

  • contacting a polymeric feed composition with an inorganic salt catalyst to produce a total product that includes liquid product mixture which is a liquid at 25°

    C. and 0.101 MPa, the inorganic salt catalyst wherein the inorganic salt catalyst has a heat transition in a temperature range between 200°

    C. and 500°

    C., as determined by differential scanning calorimetry (DSC), at a rate of 10°

    C. per minute; and

    , controlling contacting condition such that during the contacting at most 0.25 grams of hydrocarbons that are not condensable at 25°

    C. and 0.101 MPa are formed per gram of polymeric feed, as determined by mass balance.
