    Abstract: Provided is a rubber composition comprising an inorganic filler, a compound having at least one group A reacting with a rubber and two or more groups B adsorbing on the inorganic filler described above in the same molecule, a compound having the group A reacting with a rubber and an amino group in the same molecule or acrylate or methacrylate having a specific structure and further comprising, if necessary, a silane coupling agent. This makes it possible to provide a rubber composition which is excellent in the dispersibility of an inorganic filler, so that it does not elevate a viscosity of a non-vulcanized rubber and does not damage the processability and which does not bring about roughening on the surface of a rubber and is improved in a storage modulus.

  • Patent number: 7211140
    Abstract: Aliphatic diesters of unsaturated aliphatic C10-30 dicarboxylic acids are low temperature plasticizers for PVC. PVC is plasticized by contacting it with a plasticizing effective amount of an aliphatic diester of an unsaturated aliphatic C10-30 dicarboxylic acid wherein the aliphatic portion of the diester is a saturated or unsaturated, linear or branched, cyclic or acyclic unsubstituted or hydroxy-substituted aliphatic radical having from one to 10 carbon atoms.
