  • Improving the rolling resistance of diene rubber tires by means of silane-modified polybutadienes
    Patent number: 10487195
    Abstract: The invention relates to the use of silane-modified polybutadienes in rubber mixtures, in particular for improving the rolling resistance of diene rubber tires. In particular, the invention is directed to silane-modified polybutadienes in rubber mixtures, wherein the polybutadiene comprises the 1,3-butadiene-derived monomer units and wherein the proportion of A in the entirety of the 1,3-butadiene-derived monomer units present in the polybutadiene is from 10 to 60 mol %, and wherein the sum of the proportions of B and C in the entirety of the 1,3-butadiene-derived monomer units present in the polybutadiene is from 40 to 90 mol %.

  • PROCESS FOR POLYMERIZATION OF A DIENE
    Publication number: 20130338324
    Abstract: A process for polymerization of a diene is provided. The process comprises: a) reacting the diene with hydrogen peroxide in a hydrophilic organic solvent in the presence of water to obtain a polymerization reaction mixture; b) contacting the polymerization reaction mixture with water having a temperature of from 20 to 80° C. to form a mixture having an organic phase and an aqueous phase; c) removing unreacted gaseous diene from the water mixture obtained in b); d) separating the aqueous phase comprising the hydrophilic solvent from the organic phase of the water mixture; and e) distilling volatile materials from the separated organic phase from d) to obtain the polymerization product; wherein a temperature of the reaction a) is from 50-150° C.
