Abstract
A composition for crosslinking olefin polymers including an olefinically unsaturated alkoxysilane, a free radical generator, and an organic hindered amine light stabilizer compound, together with a process for crosslinking olefin polymers comprising blending said composition with an olefinic polymer, allowing the silane to graft to the polymer, and causing the grafted polymer to crosslink, preferably by subjecting it to moisture in the presence of a hydrolysis/condensation catalyst.
