  • Rubber composition
    Patent number: 10882983
    Abstract: The present invention relates to polymer blend that includes (a) 50 to 90 percent by weight of a first elastomeric polymer having a high molecular weight, (b) 5 to 50 percent by weight, preferably 5 to 40 percent by weight, more preferably 10 to 35 percent by weight, of a second elastomeric polymer having a low molecular weight and being coupled, wherein the amounts of the components (a) and (b) are based on the total weight of the polymer blend.

  • Process to remove silanol from the preparation of a modified polymer
    Patent number: 8952100
    Abstract: The invention provides a method for a preparation of a polymer selected from the following: (a) modified interpolymer comprising, in polymerized form, a conjugated diene and an aromatic alpha-olefin, or (b) a modified polymer comprising, in polymerized form, a conjugated diene; and wherein said method comprising at least the following steps: polymerizing monomers comprising at least one conjugated diene monomer in at least one polymerization reactor, in the presence of at least one solvent, to form the polymer, optionally coupling a fraction of the polymer chains using at least one coupling agent, modifying the polymer with at least one modifying agent, in at least one reactor, in the presence of the at least one solvent, to form a modified polymer solution; optionally, contacting the modified polymer solution with at least one proton donating compound; contacting the modified polymer solution with water; removing the at least one solvent; contacting the removed solvent with at least one material that will re
