Ultra high cis polybutadiene by monomeric neodymium catalyst and its tensile and dynamic properties

The vulcanized properties of different microstructured polybutadienes were measured. Linear polymer, Nd-BR1, showed excellent tensile and dynamic properties such as low heat build-up and high abrasion resistance. However, poor processibility in view of high compound viscosity and hardness was obtained. Nd-BR2, designed to compromise both processibility and physical properties, exhibited improved processibility in terms of low compound viscosity with good tensile and dynamic properties.
