摘要:
The present invention relates to a rubber composition containing silica reinforcement and to pneumatic tires having treads comprised of such rubber composition. A rubber composition comprises at least one elastomer, silica, carbon black and a silica coupler comprised of 3,3'-tetrathiodipropanol polysulfide mixture.
摘要:
This invention relates to a novel class of polymeric compositions which have molecular weights ranging from 300 to 10,000 and are the reaction product of (a) an N-aryl or N-alkaryl substituted diphenyldiamine and (b) a conjugated or nonconjugated diene. These polymeric N-aryl substituted and N-alkaryl diphenyldiamine compounds are particularly useful as an antioxidant in diene containing polymers.

摘要:
This invention discloses a process for manufacturing an elastomeric article by liquid injection molding, said process comprising the steps of: (I) heating a curable composition comprised of (1) a liquid polymer comprised of repeat units that are derived from a conjugated diolefin monomer, wherein said liquid polymer has a weight average molecular weight which is within the range of 5,000 to 100,000, and wherein the liquid polymer is functionalized with an amine moiety, (2) a carbonyl inhibited platinum catalyst, and (3) a tetrakis(dialkyl siloxy) silane crosslinking agent, to a temperature which is within the range of 30° C. to 100° C.; (II) injecting the heated curable composition into a mold at a temperature which is within the range of 100° C. to 210° C. to produce the elastomeric article; and (III) removing the elastomeric article from the mold.
摘要:
The present invention relates to a rubber composition which contains reinforcement selected from at least one of synthetic amorphous silica, carbon black and silica treated carbon black, non-alkoxysilane containing coupling agent, wherein at least one of said reinforcements is pre-treated prior to its addition to said rubber composition with at least one of an alkylsilane hydrophobating agent and/or non-alkoxysilane containing coupling agent, and to articles of manufacture, including tires, having at least one component comprised of such rubber composition.
