    摘要: The invention includes a process for inhibiting deterioration in an olefin polymer by adding a phenolic free radical inhibitor during or before polymerization with a metallocene type transition metal catalyst without inactivating the free radical inhibitor because does not inhibit the transition metal catalyst activity. Preferably the free radical inhibitor is first to remove compounds which inhibit catalyst activity. The invention also includes a composition comprising at least one olefin monomer, a polymer of the monomer, a metallocene type transition metal catalyst and at least one free radical inhibitor having sufficient substituents to hinder the active inhibiting group such that it does not undesirably inhibit the transition metal catalyst.

    摘要: A method for making a high silica loaded polymeric composition by forming a pretreated silica by creating an aqueous slurry with a silica and a silane, mixing a solvent with the silane and adding the mixture to the silica, or spraying silane on the silica allowing the liquids to be absorbed into the silica. The method includes coupling the silane onto the silica, adding the pretreated silica to a carrier, forming a slurry, heating the slurry, and mixing preheated polymeric rubber latex with the heated slurry to form a latex slurry, then blending a coagulant with the latex slurry while stirring and allowing coagulation of the latex slurry to form the high silica loaded polymeric rubber composite.
