Patent number: 7109261Abstract: 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: September 8, 2003Date of Patent: September 19, 2006Assignee: Rohm and Haas CompanyInventors: Tod C. Duvall, Paul B. Adams, Gene K. Norris

Patent number: 7077981Abstract: The invention relates to stabilizer systems, containing at least: a) a perchlorate salt; b) at least one or more compounds from the group consisting of carbamides, indole derivatives and enamines of formula (I), wherein n=1 or 2 and X=O or NR1; n=3–6 and X=O; R1=H, C1–C4-alkyl, C2–C6-alkenyl, C6–C10-aryl, C7–C18-alkaryl or C7–C18-aralkyl; R2 (if n=1)=C1–C22-alkyl, C2–C22-alkenyl or aryl, preferably phenyl, optionally substituted with up to 3 hydroxy, C1–C4-alkoxy or C1–C9-alkyl; or R2 (if n=2–6)=linear or branched C1-22-alkylene, optionally interrupted by one or more O or S atoms, wherein R2 (if n=3) can also be a C2–C3-alkyl trisubstituted isocyanurate; if X=NH R2 can also be H. Said stabilizer systems are suitable for stabilizing halogen-containing polymers, more particularly PVC.Type: GrantFiled: December 12, 2001Date of Patent: July 18, 2006Assignee: Crompton Vinyl Additives GmbHInventors: Wolfgang Wehner, Hans-Helmut Friedrich

Patent number: 7025904Abstract: Flexible and semi-rigid vinyl chloride resin compositions comprising a combination of a latent mercaptan and a zinc salt of oxidized polyethylene (a zinc ionomer) as a heat stabilizer are substantially free from the offensive odor typically associated with mercaptans and are protected during processing by the degradation products of the latent mercaptan and the zinc ionomer. The oxidized polyethylene is split out from the ionomer to act as an adhesion promoter for aqueous inks and paints, and the residual zinc carboxylate functions as a co-stabilizer with the latent mercaptan in the composition. The latent mercaptan is exemplified by a 2-S-(tetrahydropyranyl)thioalkanol, a carboxylic acid ester thereof, a 2-S-(tetrahydropyranyl)-thiocarboxylic acid, an ester thereof, and the furanyl homologs of each.Type: GrantFiled: September 4, 2003Date of Patent: April 11, 2006Assignee: Rohm and Haas CompanyInventors: Tod C. Duvall, Jeffery L. Carpenter
