Silane-grafted polyolefin composition comprising a brominated, flame retardant additive is prepared by a process comprising the step of contacting within a reaction-extrusion zone operated at grafting conditions:
A. A polyolefin,B. A hydrolysable unsaturated silane,C. A free radical generator, andD. Halogenated polyaryl alkane, e.g., decabromodiphenyl ethane,
such that at least a portion of the hydrolysable unsaturated silane is grafted to the polyolefin. The silane-grafted polyolefin is crosslinked after extrusion from the zone, typically as a wire and cable coating, upon exposure to moisture. |
