22 Nov 1977TL;DR: In this paper, an improved phosphite stabilizer for polymers, especially vinyl chloride polymers and olefin polymers was proposed. The improvement comprises the presence in such phosphite composition of a small proportion of triisopropanolamine.
Abstract: An improved phosphite stabilizer for polymers, especially vinyl chloride polymers and olefin polymers. The phosphite is either a dialkylpentaerythritol diphosphite or a polyalkyl bisphenol-A polyphosphite; the improvement comprises the presence in such phosphite composition of a small proportion of triisopropanolamine.

3 Oct 1997TL;DR: In this article, a homogeneous blended additive is used as a processing stabilizer for polymers which is a blend of Component (a), a defined phosphite or phosphonite; and Component (b) which is micronized zinc oxide.
Abstract: A homogeneous blended additive useful as a processing stabilizer for polymers which is a blend of Component (a), a defined phosphite or phosphonite; and Component (b) which is micronized zinc oxide. Component (b) is preferably in an amount of 5 to 10% based on the weight of component (a). This additive composition improves the resistance of phosphites and phosphonites against hydrolysis in the presence of moisture, by providing Component (b) as a hydrolysis stabilizer for Component (a).

TL;DR: This review will discuss some public patents and relevant papers on the flame retardancy and the thermal stability of LDH/polymer composites when the LDHs with different chemical compositions are used as the additive in the polymer matrix.
Abstract: Layered double hydroxides (LDH) has wide applications as non-toxic and halogen-free flame retardant for various resins and highly efficient thermal stabilizer for halogen-containing polymers. This review will discuss some public patents and relevant papers on the flame retardancy and the thermal stability of LDH/polymer composites when the LDHs with different chemical compositions are used as the additive in the polymer matrix. We have summarized these related LDHs in two tables: one for flame retardant and the other for thermal stabilizer.

19 Dec 2006TL;DR: In this article, a method of making a stabilizer for polymers is described, where zinc oxide (ZnO) nanoparticles are provided as an additive to a polymeric material, thereby forming a stabilized polymer composite in which the ZnO nanoparticles remain dispersed and have an average size of no more than about 15 nanometers.
Abstract: A composition and method of making a stabilizer for polymers. The composition has zinc oxide (ZnO) nanoparticles dispersed and having an average size of no more than about 15 nanometers, wherein the ZnO nanoparticles are provided as an additive to a polymeric material, thereby forming a stabilized polymer composite in which the ZnO nanoparticles remain dispersed and have an average size of no more than about 15 nanometers. The stabilized polymer composite is stabilized against heat and ultraviolet light. The polymeric material can be a (meth)acrylic resin, a styrenic resin, a pre-cure epoxy resin, or combinations thereof. In a concentrated form, the composition has ZnO nanoparticles that are typically less than 20% of the stabilized polymer composite. The stabilizer is polymerizable and may include additional additives.
