  • HIGHLY FUNCTIONALIZED STABLE HYDROCARBYLOXYSILYL POLYDIENES AND POLYDIENE COPOLYMERS
    Publication number: 20250179221
    Abstract: A polymeric composition comprising a plurality of functionalized polymers, where the plurality includes monohydrocarbyloxysilyl-functionalized polydienes and/or polydiene copolymers and dihydrocarbyloxysilyl-functionalized polydienes and/or polydiene copolymers, the polymeric composition having an aged Mooney (ML1+4@100° C.) of about 40 to about 105, where greater than 60 mole percent of polymer within the polymeric composition are functionalized, and where plurality includes about 15 to about 70 mole percent of the plurality of functionalized polymers are monohydrocarbyloxysilyl-functionalized polydienes and/or polydiene copolymers with the balance including dihydrocarbyloxysilyl-functionalized polydienes and/or polydiene copolymers.

  • Modified high-cis polybutadiene polymer, related methods and tire components
    Patent number: 12264232
    Abstract: Disclosed herein area process for preparing a modified high-cis polybutadiene polymer, a modified high-cis polybutadiene polymer, and tires having a component made using the modified high-cis polybutadiene polymer. The processes make use of a functionalizing compound of formula (I) to prepare the modified high-cis polybutadiene from a quantity of 1,3-butadiene monomer using a specified catalyst system.

  • HIGHLY FUNCTIONALIZED STABLE DIHYDROCARBYLOXYSILYL POLYDIENES AND POLYDIENE COPOLYMERS
    Publication number: 20250092168
    Abstract: A polymeric composition comprising a plurality of hydrocarbyloxysilyl-terminated polydienes or polydiene copolymers, the polymeric composition having an aged Mooney (ML1+4@100° C.) of about 40 to about 105, where the polymeric composition includes from about 10 to about 95 mole % of said hydrocarbyloxysilyl-terminated polydienes or polydiene copolymers, where said hydrocarbyloxysilyl-terminated polydienes or polydiene copolymers are formed by reacting reactive polydienes or polydiene copolymers with a dihydrocarbyloxysilyl terminating agent.
