Abstract

Crosslinkable interpolymer blends comprising ethylene monomer residues, residues of comonomers having carboxylic acid and/or carboxylic acid anhydride functionality, and residues of comonomers having epoxide functionality, a peroxide initiator, and optionally a crosslinking catalyst, which, in embodiments, cure to a gel content of greater than (>) 50 wt % within less than 1.5 minutes at 200˜C, and require little or no degassing after crosslinking.
