Abstract:
1. A method for preparing a polymeric composition, the method comprising: (i) introducing a functionalized polymer and a filler to form a blend; (ii) mixing the blend under conditions to achieve a temperature of from 160° C. to 220° C., where said mixing takes place for a time duration t; (iii) adding to the blend, after a time 0.5t, additional polymer; (iv) cooling the blend including functionalized polymer, filler, and additional polymer; and (v) introducing to the blend including functionalized polymer, filler, and additional polymer a curative and mixing the blend including functionalized polymer, filler, additional polymer, and curative under conditions to achieve a temperature of from about 75° C. to 120° C. to thereby form a vulcanizable composition of matter.
