TIRE INCORPORATING A RUBBER COMPOSITION INCLUDING A SPECIFIC HYDROCARBON RESIN

摘要

Described herein are tires comprising a rubber composition based on at least an elastomer and a hydrocarbon resin, wherein the hydrocarbon resin is based on a cyclic monomer selected from the group consisting of a distillation cut from a petroleum refinery stream, and/or C4, C5 or C6 cyclic olefins and mixtures thereof, and wherein the hydrocarbon resin has a content of aromatic protons (H Ar, expressed in mol %), a glass transition temperature (Tg, expressed in ° C.), and a number average molecular weight (Mn, expressed in g/mol) that are represented by (1) H Ar>6 mol %, (2) Tg≥95−2.2*(H Ar), and (3) Tg≥−53+(0.265*Mn).
