Abstract:

A process for making a flame retardant olefin polymer material comprising: a) preparing a polymer mixture comprising: I. about 70.0 to about 98.0 wt % of a reactive, peroxide-containing olefin polymer material (A); II. about 1.5 to about 22.5 wt % of at least one non-polymerizable halogenated flame retardant containing at least one aliphatic, unsaturated carbon-carbon bond; and III. about 0.5 to about 7.5 wt % of at least one metal synergist; wherein the sum of components I+II+III is equal to 100 wt %; b) extruding or compounding in molten state the polymer mixture, thereby producing a melt mixture; and optionally c) pelletizing the melt mixture.
