The structure and properties of industrialized BR9101N of Dushanzi petrochemical com-pany was studied,and compared with similar products of LANXESS company and nickel polybutadiene rubber.The results showed that the Mooney viscosity of NdBR9101N and CB24 was basically equiva-lent,the cis-1,4 content of BR9101N was basically the same as that of CB24,reaching more than 96％,and the cis-1,4 content of BR9000 was slightly lower;The mechanical properties of BR9101N were better than BR9000 and slightly higher than that of CB24;The tear strength of BR9101N was slightly better than that of BR9000 and CB24;The compression heat generation and rebound of BR9101N were the lowest.The abrasion resistance of BR9101N was equivalent to that of CB24 and better than that of BR9000;The aging resistance of BR9101N was equivalent to that of CB24 and bet-ter than that of BR9000.
