PREPARATION OF VULCANIZABLE COMPOSITIONS USING POLYMER-FILLER COMPOSITES
A method for preparing a vulcanizable composition of matter, the method comprising (i) providing a polymer-filler composite, where the polymer-filler composite includes particulate filler dispersed in a first elastomeric composition; (ii) providing a second elastomeric composition; (iii) mixing the polymer-filler composite and the second elastomeric composition to form an initial blend, where said mixing takes place at a mix energy sufficient to provide a drop temperature of from about 100 to about 150 °C; and (iv) introducing a cure system to the initial blend to form a curative-containing composition; (v) mixing the curative-containing composition to form the vulcanizable composition of matter, where said final mixing takes place at a mix energy sufficient to provide a drop temperature of from about 60 to about 120 °C.
