Patent number: 5504159Abstract: The present invention relates to a composition which exhibits antiozonant activity in diene containing rubbers comprising the reaction product of a multi-step process comprising:(1) reacting under condensation conditions an aldehyde and an amine containing compound to form a condensation product, whereinsaid aldehyde is selected from the group consisting of formaldehyde, acetaldehyde or mixtures thereof; andsaid amine containing compound is selected from the group consisting of: N,N'-di-substituted-p-phenylene diamines of the structural formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently selected from the group of radicals consisting of alkyls having 3 to 12 carbon atoms, aryls having 6 to 12 carbon atoms and aralkyls having 7 to 12 carbon atoms; and wherein said condensation conditions include:(i) the presence of an acid catalyst,(ii) a mole ratio of aldehyde to amine containing compound ranging from about 1.Type: GrantFiled: January 11, 1995Date of Patent: April 2, 1996Assignee: The Goodyear Tire & Rubber CompanyInventors: Budd H. Sturm, Joseph A. Kuczkowski, Paul H. Sandstrom, George F. Balogh

Patent number: 5319047Abstract: The present invention relates to a process for the preparation of N-(hydroxyphenyl)maleamic acid and various dimers and oligomers thereof. The process is characterized by heating, in the absence of any solvent, N-(hydroxyphenyl)maleamic acid at a temperature ranging from about 150.degree. to about 250.degree. C. in the presence of an acid catalyst. This unique process avoids the need to recover expensive highly polar solvents. The present invention also relates to use of these maleimide containing compounds in rubber. The use of the blend of hydroxyphenyl maleimide and the various dimers and low molecular weight oligomers impart superior properties to rubber when compared to the use of hydroxyphenyl maleimide alone in rubber.Type: GrantFiled: August 27, 1993Date of Patent: June 7, 1994Assignee: The Goodyear Tire & Rubber CompanyInventors: Lawson G. Wideman, Gordon R. Schorr, George F. Balogh, Denise J. Keith

Patent number: 5194513Abstract: The present invenion relates to rubber compositions containing a hydroxy-aryl substituted maleamic acid. The rubbers modified with the hydroxy-aryl substituted maleamic acid exhibit improved rubber/filler interaction. The hydroxy-aryl substituted maleamic acid may also be used as a replacement for resorcinol in rubber compositions and function as a methylene acceptor for reaction with conventional methylene donors.Type: GrantFiled: October 24, 1991Date of Patent: March 16, 1993Assignee: The Goodyear Tire & Rubber CompanyInventors: Lawson G. Wideman, Paul H. Sandstrom, George F. Balogh, Denise J. Keith

Patent number: 5171789Abstract: The present invention relates to poly(oxydiphenylamines) of the formula: ##STR1## wherein n is an integer ranging from about 1 to 100. The poly(oxydiphenylamines) are useful as a rubber additive and have shown improvement in the tear strength of the rubber as measured by increased peel adhesion.Type: GrantFiled: November 21, 1991Date of Patent: December 15, 1992Assignee: The Goodyear Tire & Rubber CompanyInventors: Lawson G. Wideman, George F. Balogh, Denise J. Keith

Patent number: 4843120Abstract: 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.Type: GrantFiled: September 29, 1986Date of Patent: June 27, 1989Assignee: The Goodyear Tire & Rubber CompanyInventors: Adel F. Halasa, Bill B. Gross, Joel L. Cox, George F. Balogh

Patent number: 4730025Abstract: Metals from Groups I and II of the periodic table are commonly used to initiate the polymerization of conjugated diolefin monomers into polymers. The polymers formed in such polymerizations are terminated with the metal used to initiate the polymerization and are sometimes referred to as living polymers. Reactive end groups can be affixed to the chain ends of such polymers by utilizing the process of this invention. Such reactive end groups can subsequently be reacted with the backbone of other polymer chains. This results in the formation of a polymer having a reduced number of dangling chain ends. The functionalizing agents which can be utilized in the preparation of such polymers include hexachlorocyclopentadiene, tetraalkylthiuram disulfides, and chlorinated phenyl fulvenes.Type: GrantFiled: September 22, 1986Date of Patent: March 8, 1988Assignee: The Goodyear Tire & Rubber CompanyInventors: Anthony J. Bell, Adel F. Halasa, Kenneth F. Castner, George F. Balogh

Patent number: 4401838Abstract: Isoprene and butadiene are purified by treating a petroleum refinery C.sub.4 stream or petroleum refinery C.sub.5 stream which contain butadiene or isoprene or relatively pure butadiene or isoprene and carbon disulfide by treatment of these streams with from about 1 to about 7 equivalents of a polyamine. The polyamine reacts with the CS.sub.2 impurity to form the dithiocarbamate salt. The hydrocarbon is then separated from the dithiocarbamate salt and any excess unreacted polyamine by water washing this stream or by flash distilling of the hydrocarbon.Type: GrantFiled: November 28, 1980Date of Patent: August 30, 1983Assignee: The Goodyear Tire & Rubber CompanyInventor: George F.
