23. A method for balancing the viscoelastic properties of a rubber composition, the method comprising incorporating 5-100 phr of at least one polymer or copolymer containing a styrene monomer with 50% to 100% modern carbon atoms into the rubber composition, wherein the viscoelastic properties balanced include rolling resistance and wet traction, and the balancing comprises either:
-
a. increasing wet traction while maintaining or decreasing rolling resistance as compared to a control rubber composition that replaces the modern carbon-containing polymer or copolymer with a polymer or copolymer containing no modern carbon atoms;
orb. increasing wet traction by more than 50% and increasing rolling resistance by less than 50% as compared to a control rubber composition that replaces the modern carbon-containing polymer or copolymer with a polymer or copolymer containing no modern carbon atoms. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
