The invention relates to an NdBR wet masterbatch comprising &#x2014;neodymium-catalyzed polybutadienes having a high proportion of cis-1,4 units of &#x3e;95% and a low proportion of 1,2-vinyl content of &#x3c;1%, with narrow polydispersity of less than 3, with a Mooney viscosity (ML100&#xb0; 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, &#x2014;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 &#x2014;an oil.

NdBR wet masterbatch

The invention relates to functionalized diene rubbers with trimethylolpropane and fatty acid, to a process for production there of and use thereof for the production of wet-skid-resistant and low-rolling-resistance motor-vehicle tire treads with high abrasion resistance.

Mixtures composed of functionalized diene rubbers with trimethylolpropane and fatty acid, a process for production thereof and use thereof

The present invention relates to rubber mixtures with functionalized diene rubbers and with microgels, to a production process, and to the use of the mixtures for the production of low-abrasion motor-vehicle tires which have wet-slip resistance and which have low rolling resistance.
