Claim Text:
1. A method of forming a composition comprising providing a filler having a particle size distribution in which over ten percent of the particles of the filler have an effective diameter of less than 1 micron; providing a coupling agent material; providing a mixer having a volume to receive material and means for mixing said material, said mixer having sealing means operable between a first position to seal said volume and a second position to unseal said volume, and said mixer having cooling means to cool the material in said volume; placing said filler and said coupling agent material in said volume; operating said sealing means to said first position to seal said volume; operating said mixer to mix and to heat said filler and said coupling agent material in said volume to a temperature at which said coupling agent changes to and becomes a gas comprised of gas particles and further operating said mixer to mix said filler with said coupling agent material to associate said gas particles with at least said particles of said filler having an effective diameter of less than 1 micron to form a blend; operating said cooling means one to cool said blend; operating said sealing means to said second position to unseal said volume; providing an acid scavenger, an anti oxidant, and a resin; and mixing said acid scavenger, said anti oxidant, said blend and resin to form one of said composition and a master batch.
