摘要:
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.

摘要:
A golf ball consisting of a core including a base rubber and a halogenated organosulfur compound; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer including a base rubber and an organosulfur compound, and having a thickness of 0.09 inches to 0.18 inches; wherein the core has a PGA compression of 60 or greater and the golf ball has a coefficient of restitution of about 0.8 or greater when measured at an incoming velocity of about 125 ft/s.
摘要:
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. The latent mercaptans also serve as intermediates in the preparation of anti-oxidants, anti-microbial agents, photostabilizers, and primary heat stabilizers. Highly effective heat stabilizers are prepared by the condensation of formaldehyde and a para-phenol and further condensation of the crude product with a mercapto-containing compound.
