Abstract
A curable composition comprising an ethylene-containing polymer, a curing agent, and a mineral filler treated with tetramethyltetravinylcyclotetrasiloxane, is compounded and fabricated to the desired shape, such as an insulation layer over a conductor. The fabricated product is then passed through a non-aqueous heat transfer medium maintained at about atmospheric pressure and at a temperature sufficient to effect curing in situ of the ethylene-containing polymer. The resulting cured composition is characterized as relatively dense (substantially non-porous) especially suitable for use as insulation for wire and cable.
