The selection of the oil-extending process and properties of Nd-catalyzed oil-extended

1,4-cis-polybutadiene (in English)

Summary

Three methods of oil-extending of the rubber - continuous, one-step and two-step ones have been discussed. Two-step method, leading to the product showing constant, required oil content, appeared to be the best one. This way modified rubber (Nd-catalyzed 1,4-cis-polybutadiene) shows better mechanical properties than Nd-catalyzed 1,4-cis-polybutadiene, the best butadiene rubber up to now.
