摘要：
Embodiments of 1,4-polybutadiene rubber compositions useful at low temperatures are provided, wherein the 1,4-polybutadiene incorporated therein comprises a cis content of at least 85 to about 92%, a vinyl content of at about 1% to about 5%, and a trans content of about 3 to about 12%, and wherein the 1,4-polybutadiene has an enthalpy of melting ΔHm of about 5 to about 25 J/g° C. as measured via differential scanning calorimetry (DSC).
