Patent number: 6180707Abstract: The process of this invention can be utilized to stabilize tin-coupled rubbery polymers. This process involves adding a chelating diamine or a metal salt of a cyclic alcohol to the rubbery polymer after the tin coupling has been carried out. This invention more specifically discloses a process for improving the stability of a tin-coupled rubbery polymer which comprises adding a metal salt of a cyclic alcohol to the tin-coupled rubbery polymer subsequent to the time at which the tin-coupled rubbery polymer is coupled. The use of metal salts of cyclic alcohols does not lead to recycle stream contamination because they do not co-distill with hexane or form compounds during steam-stripping which co-distill with hexane. In other words, the boiling points of these metal salts of cyclic alcohols are very high, so they do not co-distill with hexane and contaminate recycle streams. Additionally, metal salts of cyclic alcohols are considered to be environmentally safe.Type: GrantFiled: December 1, 1999Date of Patent: January 30, 2001Assignee: The Goodyear Tire & Rubber CompanyInventors: Wen-Liang Hsu, Adel Farhan Halasa

Patent number: 5051311Abstract: A curable coating composition, which provides excellent corrosion protection to metals, is disclosed. The composition comprises (I) a reaction product (or blend) of a resinous copolymeric siloxane solution with a liquid organohydrogenpolysiloxane, (II) a hydroxy-functional diorganopolysiloxane, (III) an organosilane, (IV) a trialkyl orthoformate, (V) an organic titanate and (VI) a condensation catalyst. High solids compositions of the present invention can be applied by conventional siphon cup spray equipment and have an extended bath life relative to prior art formulations of this type.Type: GrantFiled: March 1, 1990Date of Patent: September 24, 1991Assignee: Dow Corning CorporationInventors: Paul J. Popa, Arthur J. Tselepis, Harold L. Vincent
