Patent number: 4898614Abstract: A polish formulation containing as components at least one member selected from the group consisting of waxes, solvents, surfactants, thickening agents, abrasives, dyes, odorants, and other ingredients normally used in making polishes, and as an improvement incorporating a composition which is the reaction product of an acid anhydride and an aminofunctional siloxane. The resulting zwitterionic aminofunctional siloxane can, if desired, be further reacted with a strong acid to provide an equilibrium of the zwitterion and a conjugate acid base pair of the zwitterion and the acid. The invention also includes a method of sheeting water on a surface with the polish, a method of making an aminofunctional siloxane zwitterionomer, and an aminofunctional zwitterionomeric siloxane compound which is the reaction product.Type: GrantFiled: January 5, 1989Date of Patent: February 6, 1990Assignee: Dow Corning CorporationInventors: Daniel J. Halloran, Kenneth A. Kasprzak, Stefano G. Savastano, Terence J. Swihart

Patent number: 4778909Abstract: Fast high resolution separations of biopolymers with retention of biological activity have been achieved by hydrophobic interaction chromatography using trialkoxy silyl ethers of the general formula(RO).sub.3 Si--(CH.sub.2).sub.m --O--(CH.sub.2 CH.sub.2 O).sub.n --(CH.sub.2).sub.p R'chemically bonded to silica-based chromatographic supports. In the formula R is alkyl of from one to five carbons, m is an integer from two to five, n is an integer from one to five, p is an integer from zero of ten, and R' is methyl, phenyl, or substituted phenyl. Stable and reproducible bonded phases are prepared in a novel solventless procedure by a bonding process which uses a defined and controlled amount of water on the silica surface and a gaseous or volatile basic catalyst such as ammonia to produce a controlled amount of silane polymerization and cross-linking in addition to extensive bonding between silane and silica.Type: GrantFiled: May 11, 1984Date of Patent: October 18, 1988Assignee: Northeastern UniversityInventors: Barry L.
