    Abstract: 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.

    Abstract: 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.

  • Patent number: 6919392
    Abstract: The heat and light stability imparted to vinyl halide polymers by metal compounds conventionally employed for this purpose is considerably improved by the presence of a mercapto ester such as 2-mercaptoethyl stearate. The esters can replace a substantial portion of the metal compound with no significant reduction in stability.

  • Patent number: 6897254
    Abstract: Halogen-containing polymer compositions containing a heat stabilizer comprising a latent mercaptan, a zinc salt, and a free mercaptan as a separate entity are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan. A free mercaptan is among those products. The separate free mercaptan (i.e., an alien free mercaptan) enhances the activity of the latent mercaptan in a synergistic manner.
