Patent number: 6818236Abstract: Conventional SBR does not have the soft and smooth chew characteristics needed in chewing gum base for soft chew applications. Conventional SBR typically also has undesirable odor and taste characteristics that have generally limited its use in chewing gum base formulations. However, there is a desire to use SBR in such applications because it is relatively inexpensive. The present invention also specifically discloses a process for synthesizing styrene-butadiene rubber that is particularly useful in manufacturing chewing gum base for soft chew applications which comprises copolymerizing about 1 phm to about 12 phm styrene and about 88 phm to about 99 phm of 1,3-butadiene in an aqueous emulsion, wherein said copolymerization is conducted at a temperature which is within the range of about 1° C. to about 20° C.Type: GrantFiled: June 11, 2002Date of Patent: November 16, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Valerie Anne Hill, Gerald Owen Schulz

Patent number: 6403687Abstract: The subject invention relates to a process for coating aggregate which is particularly useful in making asphalt concrete to provide the aggregate with a high level of resistance to stripping by water, which comprises: (1) mixing the aggregate with latex to form a latex/aggregate mixture, wherein said latex is comprised of water, an emulsifier, a polymer and a water-soluble divalent metal salt; (2) heating the latex/aggregate mixture to a temperature which is within the range of about 66° C. to about 232° C.; (3) maintaining the latex/aggregate mixture at said elevated temperature for a time which is sufficient to reduce the moisture content of the latex/aggregate mixture below about 0.7 weight percent and to allow the polymer in the latex to crosslink on the surface of the aggregate to produce the coated aggregate.Type: GrantFiled: January 6, 2000Date of Patent: June 11, 2002Assignee: The Goodyear Tire & Rubber CompanyInventors: Gerald Owen Schulz, Alan Lee Bethel

Patent number: 6344514Abstract: This invention relates to fire retardant latex binders for non-woven fabrics. Non-woven fabrics can be manufactured using the fire retardant latex binder formulations of this invention using cotton fibers, polyester fibers, rayon fibers, nylon fibers, cellulosic fibers, fiber glass or various mixtures of such fibers. The fire retardant latex binders of this invention are particularly useful in manufacturing fiber glass furnace filters. The fire retardant latex binders of this invention are comprised of (1) water, (2) a styrene-butadiene rubber, (3) a fatty acid soap, (4) a sulfonate surfactant, (5) an ethylene oxide/propylene oxide/ethylene oxide triblock polymer, wherein the ethylene oxide/propylene oxide/ethylene oxide triblock polymer has a number average molecular weight of at least 8000, and (6) about 10 phr to about 50 phr of diammonium phosphate.Type: GrantFiled: February 22, 2001Date of Patent: February 5, 2002Assignee: The Goodyear Tire & Rubber CompanyInventor: Gerald Owen Schulz
