Abstract
This disclosure relates to wear-resistant rubber compositions, such as those, for example, comprising at least one hydroxy-terminated polybutadiene, at least one natural rubber, at least one polymerization accelerant; at least one sulfur; and at least one polybutadiene, wherein the wear-resistant rubber composition may have an effective cross-linking density of at least about 30×10−5 moles/cm3.
