Estimating the term…
Steel cables are utilized for reinforcing a wide variety of rubber articles. For instance, pneumatic tires are normally reinforced with steel tire cords. It is important for such reinforcing cables to exhibit good fatigue and corrosion resistance. It has been unexpectedly found that the fatigue and corrosion resistance of such cables can be improved by incorporating syndiotactic-1,2-polybutadiene into the interstices between the steel filaments in such cables. This invention more specifically relates to a cable for reinforcing rubber articles having improved fatigue and corrosion resistance which is comprised of a plurality of steel filaments and syndiotactic-1,2-polybutadiene, wherein the syndiotactic-1,2-polybutadiene is dispersed within interstices between said steel filaments.
