    摘要: Thiocarbonate compounds which, in one embodiment, are utilized as a rheology modifier or associative thickener. The thiocarbonate compounds thicken or increase the viscosity of a composition, preferably an aqueous composition when used in an effective amount. In one preferred embodiment, the thiocarbonate compounds include at least one hydrophilic group containing repeat unit such as derived from acrylic acid, and at least one hydrophobic group to enhance association with other compounds and thus increase viscosity of a composition. Aqueous composition comprising a latex and thiocarbonate associative thickeners are described.

    摘要: A composition is disclosed having minimum halogen content, fire-retardance and/or drip-resistant characteristics. The composition comprises an effective amount of a polycarbonate, a glass fiber, a polysiloxane-polycarbonate copolymer, and a synergistic combination of an aromatic sulfone sulfonate such as potassium diphenylsulfone sulfonate with an aromatic sulfonate such as sodium salt of toluene sulfonic acid, optionally in the presence of an anti-drip agent. The polycarbonate composition is useful for manufacture of electronic and mechanical articles, among others.

    摘要: A thin, light-weight, flexible sheet product useful for the manufacture of radiation attenuation garments. The sheet product is a polymeric material and includes a heavy loading of high molecular weight metal particles. The sheet product is formed from a polymer latex dispersion into which a high molecular weight metal particles are dispersed, where the latex retains a sufficiently low viscosity to be pourable and allow casting of the sheet product.

    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.
