| 摘要 |
A method for treating polymers of ethylene which have been stabilized with hindered phenolic stabilizer to reduce the discoloration produced upon processing the stabilized polymer at elevated temperature wherein before completion of the processing at elevated temperature there is admixed with the stabilized polymer compositions at least one compound chosen from the group consisting of aliphatic hydroxy compounds and epoxy-containing compounds. In a preferred embodiment, the polymer of ethylene and aliphatic hydroxy compound are further admixed with water. In another embodiment of the invention the aliphatic hydroxy compounds contain from 1 to 4 hydroxyl groups and are water soluble. A treated polymer of ethylene stabilized with hindered phenolic stabilizer that has been admixed with a compound chosen from the group consisting of aliphatic hydroxy compounds and epoxy-containing compounds. A composition of matter comprising a polymer of ethylene, hindered phenolic stabilizer, aliphtic hydroxy compound, and water.
