  • Patent number: 5616653
    Abstract: The subject invention discloses a process for preparing a coupled styrene-isoprene-butadiene rubber which is particularly valuable for use in making automobile tire tread rubber compounds which comprises the steps of (1) solution terpolymerizing in an organic solvent from about 5 weight percent to about 40 weight percent styrene, from about 1 weight percent to about 10 weight percent isoprene, and from about 50 weight percent to about 94 weight percent 1,3-butadiene, based on total monomers, to a conversion of at least about 90% to produce a living styrene-isoprene-butadiene polymer, wherein the terpolymerization is initiated with an organolithium compound, and wherein the terpolymerization is conducted in the presence of a polar modifier at a molar ratio of the polar modifier to the organolithium compound, which is within the range of about 0.5:1 to about 5:1, and wherein the terpolymerization is conducted at a temperature which is within the range of about 20.degree. C. to about 150.degree. C.

  • Patent number: 4843120
    Abstract: It has been determined that certain rubbery polymers having multiple glass transition temperatures can be utilized in making tires which have improved rolling resistance, improved wet skid resistance, and outstanding tread wear. These rubbery polymers are derived from at least one conjugated diolefin monomer, have a first glass transition temperature which is between -110.degree. C. and -20.degree. C. and have a second glass transition temperature which is between -50.degree. C. and 0.degree. C. These rubber polymers can be homopolymers of conjugated diolefin monomers, copolymers of more than one conjugated diolefin monomer, or copolymers derived from at least one conjugated diolefin monomer and at least one vinyl aromatic monomer.

  • Patent number: 4137392
    Abstract: Copolymers of at least two acrylate monomers such as isobutyl methacrylate and 2-ethylhexyl acrylate, an organic acid or acid anhydride, and N-vinyl-2-pyrrolidone are prepared by emulsion polymerization. The polymer is then coagulated and dried, and dry resin is mixed with a water miscible coalescing solvent and a volatile amine. The amine-treated resin is water reducible and when used as a coating resin produces coatings of unusual water resistance and adhesion to metal surfaces.
