标 题:Removal of acrylonitrile from latex with saturated heterocyclic amines
发明人：SENYEK MICHAEL L
权利人:GOODYEAR TIRE & RUBBER
摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with saturated 6 to 7 membered ring heterocyclic amines. These amines react with acrylonitrile by a nitrogen-cyanoethylation reaction which results in the formation of a tertiary amino linkage.

摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with oximes. Oximes react with acrylonitrile by an oxygen-cyanoethylation reaction which results in the formation of a cyanoethyl oximino ether linkage.

标题:Surfactantless synthesis of amphiphilic cationic block copolymers
发明人：PARKER DANE KENTON; KULIG JOSEPH JOHN
权利人:GOODYEAR TIRE & RUBBER
摘要:The present invention is directed to a method of producing an amphiphilic block copolymer, including the steps of:n (1) preparing a first aqueous polymerization medium which is comprised ofn (a) 4-vinylpyridine, (b) a trithiocarbonate RAFT agent, and an emulsifier, wherein the emulsifier is prepared in-situ within the aqueous polymerization medium by the reaction of a latent surfactant with a surfactant activator; n (2) polymerizing the 4-vinylpyridine within the first aqueous polymerization medium in the presence of a first free radical initiator to produce a poly(4-vinylpyridine); (3) protonating the poly(4-vinylpyridine) to form a protonated poly(4-vinylpyridine) RAFT macroinitiator; (4) preparing a second aqueous polymerization medium which is comprised of the protonated poly(4-vinylpyridine) RAFT macroinitiator and a monomer containing ethylenic unsaturation but is exclusive of a surfactant; and (5) polymerizing the protonated poly(4-vinylpyridine) RAFT macroinitiator and monomer containing ethylenic unsaturation within the second aqueous medium in the presence of a second free radical initiator and a temperature less than 100° C. to produce an amphiphilic block copolymer of the 4-vinylpyridine and monomer containing ethylenic unsaturation.

权利人:UNIV TENNESSEE RES FOUND
摘要:Methods of preparing macromonomers, e.g., single- or double-tailed macromonomers, using radical polymerization of a first monomer in solution or in an emulsion are described. Methods of using the macromonomers in the preparation of multigraft copolymers are also described. For instance, the macromonomer prepared by radical polymerization can be used in an emulsion copolymerization with a second monomer to form a random multigraft copolymer. The random multigraft co-polymers can be superelastomers.

摘要:A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described.
