摘要： The present invention provides silica-filled, vulcanized elastomeric compounds comprising an elastomer mixed with at least a silica filler, a processing aid, and a curing agent, and processes for the preparation of the same. Generally, the present invention provides processing aids which effectively reduce or replace the amount (i.e., about 10 percent by weight based upon the silica filler) of the processing aid bis[3-triethyoxysilyl)propyl]tetrasulfide (“Si69”) used in the production of silica-filled rubber stocks. These new processing aids include alkyl alkoxysilanes, fatty acid esters of hydrogenated and non-hydrogenated sugars and the polyoxyethylene derivatives thereof, and combinations thereof, with or without various non-reinforcing fillers such as mineral fillers. The processing aids do not hinder the physical properties of the compounds and have been found to be excellent substitutes for Si69. The processing aids may be supported on the silica filler or any of the other fillers employed in the composition for improved handling, safety and performance. Processes for the preparation of the silica filled vulcanizable elastomers are provided as well as pneumatic tires employing tread stock comprising the novel vulcanizable elastomers.

摘要： A processable rubber stock is produced by the preparation of a silica-filled, vulcanized elastomeric compound comprising mixing an elastomer with an amorphous silica filler, from 0 to less than about 1% by weight based on said silica filler of bis[3-(triethoxysily)propyl]tetrasulfide, an alkylalkoxysilane and a cure agent. A further processing aid comprising at least one of an ester of a fatty acid or an ester of a polyol is preferred. The elastomer is preferably a diene monomer homopolymer or a copolymer of at least one diene and at least one monovinyl aromatic monomer. By effecting vulcanization, a vulcanized elastomeric compound is produced containing good physical properties for use as tread stock for a pneumatic tire.

摘要： Novel solid supported anionic polymerization initiators that are multiply metalated with Group IA alkali metal atoms are provided and employed to produce extremely high molecular weight branched diene polymers. The initiators are prepared by metalating a particle comprising a thermoplastic polymer or a cured elastomer in the presence of a polar coordinator. The polymers obtained by anionic polymerization employing the initiators are multiply branched, with a polymer chain covalently attached to the particle at virtually every metalation site. The macro-branched polymers exhibit desirable properties, such as an extremely high molecular weight, a controlled molecular weight distribution, T.sub.g and vinyl content, and the ability to readily absorb hydrocarbon solvents and oils. The polymers are easily compounded to form vulcanizable elastomeric compounds and articles that have excellent resistance to wear and tear and exhibit reduced hysteresis properties.

摘要： A surface stabilized, non-agglomerated silica is provided. The silica is prepared by the method of providing non-agglomerated silica, and then treating the surface of the silica, thereby substantially preventing agglomeration of silica. The surface of the silica may be treated with a hydrophobating agent, such as a silane, or an alcohol. Different embodiments of the invention illustrate that the hydrophobating agent or alcohol can be added at different points within the process of forming the surface stabilized, non-agglomerated silica. The surface stabilized, non-agglomerated silica has a size in the nanometer range. The surface stabilized, non-agglomerated silica can be used as an additive in any application that uses silica, such as reinforcing fillers for elastomeric compositions, foods, drugs, dentifrices, inks, toners, coatings and abrasives.
