Abstract: Described herein are methods for improving the color stability of a synthetic polymer composition by incorporating one or more inorganic phosphor dopants into the synthetic polymer. The inorganic phosphor dopants absorb UV light and emit the UV light as down-converted visible light, thereby producing a brighter appearance for the synthetic polymer composition. Methods for preparing the synthetic polymer compositions having improved color stability are additionally described.

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: Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of:



mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than (≥) one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and
adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.

Abstract: Heating of rubber products during processing produces odours which may be abated by commingling the rubber product with fabric softener. The fabric softener may be commingled with the rubber product via a dip tank filled with fabric softener solution, by applying fabric softener to the rubber product prior to heating/processing the rubber product, by injecting the fabric softener into an extruder that is heating/processing the rubber product, and by treating the by-product exiting the side stream of the extruder.
