ABSTRACT:
A process for the cross-linking of olefin-polymers such as polyethylene which comprises reacting the polymer with a free radical generator to form a polymer having free radicals and reacting the polymer having free radicals with a tetrafunctional organo zirconate which has at least one functional group that is reactive with the free radicals on the polymer followed by contact thereof with moisture or water, optionally in the presence of a condensation reaction catalyst.
