Abstract: This invention relates to a process for modifying an olefin polymer composition, comprising melt mixing an olefin polymer composition with a free-radical initiator composition comprising a metal peroxide powder, wherein the free-radical initiator composition initiates a free-radical reaction of the olefin polymer composition to produce a modified olefin polymer composition. The invention also relates to a modified olefin polymer composition prepared by the process and various articles formed from the modified olefin polymer composition.

Abstract: The invention relates to a process for modifying an olefin polymer composition comprising melt mixing an olefin polymer composition with a free-radical initiator composition comprising a peroxide-modified inorganic composition prepared from: i) a liquid or an aqueous hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a modified olefin polymer composition prepared by the process and various articles formed from the modified olefin polymer composition.

Abstract: The invention relates to a free-radical initiator composition for polyolefin modification comprising a peroxide-modified inorganic solid particle prepared from: i) a liquid or solution of hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a method for preparing a peroxide-modified inorganic composition, comprising mixing a liquid or solution of hydrogen peroxide and one or more inorganic solid particles to form a suspension or gel, and optionally, filtering the suspension or gel and drying the filtered materials to form a solid, peroxide-modified inorganic composition.
