Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using metal oxides and heat are described. The metal oxides improve the depolymerization reaction by decreasing the onset temperature for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.

Abstract: A solid catalyst component for the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I) wherein R1 and R7 groups, equal to or different from each other, are selected from C1-C15 hydrocarbon groups, R2 group is selected from C1-C10 hydrocarbon groups, and R3 to R6 groups, independently, are selected from hydrogen or C1-C15 hydrocarbon groups which can be fused together to form one or more cycles. The catalyst system based on the solid catalyst component is endowed with high activity and stereospecificity.
