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.

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,
- wherein the peroxide-modified inorganic composition initiates a free-radical reaction of the olefin polymer composition to produce a modified olefin polymer composition.
