Zusammenfassung: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 wtï¼ within less than 1.5 minutes at 200～C, and require little or no degassing after crosslinking. Las mezclas de interpolímeros reticulables que comprenden residuos de monómeros de etileno, residuos de comonómeros que tienen funcionalidad de ácido carboxílico y/o anhídrido de ácido carboxílico y residuos de comonómeros que tienen funcionalidad de epóxido, un iniciador de peróxido y opcionalmente un catalizador de reticulación que, en modalidades, curan a un contenido de gel de más de (>) 50% en peso en menos de 1.5 minutos a 200°C, y requieren poca o ninguna desgasificación después de la reticulación.
