Abstract: Catalytic compositions and processes for depolymerizing polyolefin-based feed into useful petrochemical products are described. The compositions are a composite of a zeolite catalyst component and a co-catalyst comprising an activated clay component and/or a solid base component. These catalyst systems, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of impurities that may be present in the polyolefin-based feed. This results in a shorter residence time in the depolymerization unit and more efficient process.

Abstract: The present disclosure relates to propylene-ethylene copolymers comprising an ethylene content of 0.1-10% by weight, a molecular weight distribution (MWD), expressed in terms of Mw/Mn, of greater than 3.0 and a xylene soluble (XS) fraction content defined by values that fall below the line given by the equation XS=1.0296·e0.435C2. The propylene-ethylene copolymers advantageously exhibit high transparency and low melting temperatures.
