Abstract: A process for the preparation of a propylene polymer containing a coloring agent, including the steps of:
(i) forming a solid mixture (a-b)of (a) a ZN catalyst component made from or containing Mg, Ti, halogen and an internal electron donor compound, and (b) a coloring agent made from or containing at least a pigment; wherein the mixture being in a weight ratio (b):(a) ranging from 0.01:1 to 0.4:1; and
(ii) feeding the mixture (a-b) to a polymerization reactor and operating the reactor under polymerization conditions to produce the propylene polymer.
wherein the process having the b:a weight ratio and a time in days elapsed between mixture formation and use in polymerization fall below the curve defined by the equation y=3+0.832x−1,17 wherein y is the time in days elapsed between mixture formation and use in polymerization and x is the (b):(a) weight ratio.

Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using supported metal oxides and heat are described. The supported metal oxides improve the depolymerization reaction by decreasing the half time 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 manhole for a polymerization unit having a through-hole formed with a shoulder matching a corresponding shoulder of a plug of a closure member operatively inserted in the through-hole. The through-hole can be closed with a minimum clearance, such that polymer particles do not deposit in the gap between the wall of the unit and the plug of the closure member.
