Abstract: Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The compositions are a composite of at least one zeolite catalyst with one or more co-catalyst(s) that is a solid inorganic material. These composite catalysts, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of non-polyolefin polymers that may be present. This results in a shorter residence time in the depolymerization unit and more efficient process.

Abstract: A polymer composition comprising: A) from 70 wt% to 95 wt% of a propylene composition comprising: A1) from 19 wt% to 50 wt% of a propylene ethylene; A2) from 50 wt% to 81 wt% of a propylene ethylene 1-butene; the sum of the amount of component A1) and A2) being 100; the composition being characterized by a xylene soluble fraction at 0/25 °C comprised between 2 wt% and 15 wt%; B) from 5.0 wt% to 30.0 wt% of a copolymer of 1-butene and ethylene containing from 3.0 wt% to 4.2 wt% of ethylene derived units.
