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: 4912160Abstract: Stable, non-aqueous solvent solutions of acid-functional polymers are prepared by:(a) reacting, in the presence of an esterification catalyst, a hydroxy-functional acrylic polymer with a cyclic carboxylic anhydride at a reaction temperature from about 35.degree. C. to about 76.degree. C. thereby forming an acid-functional polymer having ester groups and carboxylic acid groups; and(b) maintaining the reaction of the anhydride and hydroxyl groups until the desired amount of acid functionality on the acid-functional polymer has been obtained; and then(c) adding to said acid-functional polymer a stabilizing amount of a low-molecular weight alcohol solvent under conditions which will not cause substantial reaction of the solvent and the acid-functional polymer.Type: GrantFiled: November 16, 1987Date of Patent: March 27, 1990Assignee: The Sherwin-Williams CompanyInventor: Mohamad D. Shalati
