Abstract
The use of magnesium oxide for increasing the rate of crosslinking and/or the crosslinking density of at least one crosslinkable polymer is described in addition to a composition that can be employed in this use, comprising: from 30 to 80% by weight of a crosslinking co-agent, from 0.5 to 10% by weight of an organic peroxide, from 15 to 60% by weight of magnesium oxide, and from 0 to 40% by weight of one or more crosslinkable polymers. An article obtained from this composition is also described.
