Patent ID: 7754789

Claim:
A flame retardant polymer composite prepared by the method of treating at least one filler, selected from the group consisting of layered silicates and non-silicate compounds, combining said filler with an early or late transition metal first catalyst component that becomes activated for olefin polymerization when in contact with the filler, and contacting an olefin with the activated catalyst-filler combination either (a) in the absence of an alkylaluminum second catalyst component or (b) in the presence an alkylaluminum or an alkylaluminoxane second catalyst component when the first catalyst component is an early transition metal catalyst, whereby to form an filler-polyolefin composite incorporating platelets of said filler, and having flame retardant properties, wherein the silicate's layered structure is disrupted and the flame retardant properties are a result of including the filler.
