NDBR WET MASTERBATCH |
| 摘要 |
The invention relates to an NdBR wet masterbatch comprising -neodymium-catalysed polybutadienes having a high proportion of cis-1,4 units of >95% and a low proportion of 1,2-vinyl content of <1%, with narrow polydispersity of less than 3, with a Mooney viscosity (ML1-4 100° C.) between 30 and 90 MU, with a high linearity index (ratio of solution viscosity to Mooney viscosity) of 3 to 10 m Pas/MU and with a Mooney relaxation after 30 seconds of 2 to 12%, the latter being prepared by means of solution polymerization,—at least one carbon black, the carbon black having an iodine absorption number (ION) between 85 and 210 mg/g, measured to ASTM D1510-1304, and an oil absorption number (OAN) between 75 and 150 ml/100 g, measured to ASTM D2414, and—an oil. |

1. NdBR wet masterbatch comprising
neodymium-catalysed polybutadienes having a high proportion of cis-1,4 units of >95% and a low proportion of 1,2-vinyl content of <1%, with narrow polydispersity of less than 3, with a Mooney viscosity (ML1+4 100° C.) between 30 and 90 MU, with a high linearity index (ratio of solution viscosity to Mooney viscosity) of 3 to 10 mPas/MU and with a Mooney relaxation after 30 seconds of 2 to 12%, the latter being prepared by means of solution polymerization, at least one carbon black, the carbon black having an iodine absorption number (ION) between 85 and 210 mg/g, measured to ASTM D1510-1304, and an oil absorption number (OAN) between 75 and 150 ml/100 g, measured to ASTM D2414, and an oil. |
