    摘要: A method for making a silicic acid containing rubber base composition includes providing composition ingredients of rubber, silicic acid, silane and additional additives except for vulcanization ingredients. First and second mixers separate from each other are provided wherein the ingredients except for the vulcanization ingredients can be mixed. All of the composition ingredients are introduced into the first mixer except for the vulcanization ingredients simultaneously or at time intervals. The composition ingredients introduced into the first mixer are mixed to a composition. The composition formed in the first mixer is transferred directly into the second mixer without an intermediate storage thereof. The transferred composition formed in the first mixer is mixed at least almost to completion in the second mixer with the temperature lying in the temperature range of 130° C. to 180° C. at least over the greatest part of the dwell time of the composition in the second mixer wherein the silicic acid reacts acceleratedly with the silane.

    摘要: This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.
