1. A method for increasing crosslinking rate and/or crosslinking density of at least one crosslinkable polymer comprising crosslinking the at least one crosslinkable polymer in the presence of magnesium oxide, wherein the crosslinking of the crosslinkable polymer is carried out in the presence of:
a crosslinking co-agent and
an organic peroxide.
