The properties of cis-1,4-polybutadiene rubber obtained with neodymium caprate catalysts in enlarged scale are reported. The results showed that modifying agent not only affects the macro molecular chain structure, reduces molecular weight and molecular weight distribution(MWD) of the raw rubber, but also the properties of the vulcanizate therefrom. The vulcanizate has tensile strength of about 15 MPa, but good abrasion resistance, heat build-up and wet skid resistance as well as lower rolling resistance.
