oxidation of t-alcohols in water - dioxane - sodium hydroxide system has been examined. The possibility of production of t-alkoxy radicals by anodic oxidation of t-alcohols in the electrolytic system was found. The relative ease of bond scission of the intermediate t-alkoxy radical was determined by quantitative analysis of the mixture of ketones produced. The relativerates of cleavage decrease in the order:

The invention provides a process to form a second composition comprising a modified ethylene-based polymer, the process comprising the step of contacting under thermal treatment conditions a first composition comprising a first ethylene-based polymer, and the following: (A) at least one carbon-carbon (C—C) free radical initiator; and (B) at least one free radical initiator other than a C—C free radical initiator of (A) (a non-C—C free radical initiator). The melt strength of the second composition is typically at least 15% or greater than the melt strength of the first composition. The second composition typically has a gel content less than or equal to 40.
