Patent number: 6706214Abstract: A composition and process for inhibiting the corrosion of metallic substrates is revealed. The process utilizes an aqueous treatment solution comprising chitosan which has been reacted with an additive selected from the group consisting of phosphorus-containing compounds and sulfur-containing compounds and mixtures thereof. More preferably, the phosphorus-containing compound is a phosphonic acid and the sulfur-containing compound is a mercapto, thio, or thienyl containing compound or a mercapto functional silane. The composition and process are particularly useful in providing corrosion protection for aluminum and aluminum alloys.Type: GrantFiled: December 23, 2002Date of Patent: March 16, 2004Inventor: Gerald Wojcik

Patent number: 6537466Abstract: Halogen-containing polymer compositions comprising a latent mercaptan-containing heat stabilizer composition substantially free from the offensive odor typically associated with mercaptans are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan may be the sole heat stabilizer additive but the free mercaptan released during processing may also synergize the activity of metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and mercaptides in the polymer composition. The odor of primary mercaptan-containing heat stabilizers in halogenated polymer compositions is masked by a small amount of a latent mercaptan.Type: GrantFiled: August 4, 1999Date of Patent: March 25, 2003Assignee: Rohm and Haas CompanyInventors: Tod C. Duvall, Paul B. Adams, Gene K. Norris
