ABSTRACT:
Curable polymeric compositions comprising copolymers of alpha-substituted polyolefins and silarylenesiloxane-polydiorganosiloxane block copolymers which exhibit increased resistance to flow and dripping at flame temperatures. The compositions are made by blending the polyolefin with a silphenylene and optionally a filler and can be used when cured as flame-retardant insulation for wire and cable and for molded products and the like.
