摘要:Novel latex or emulsion compositions containing internally plasticizing and crosslinkable long-chain alkenol ester monomers are disclosed and claimed. Preferred embodiments include latex formed from acrylate or methacrylate esters of long-chain alkenols. A process for the synthesis of the latex composition is also disclosed, which involves (a) esterification of a long-chain alkenol with an ethylenically unsaturated carboxylic acid; (b) polymerization of the ethylenically unsaturated ester in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C. and cure to above ambient glass transition (T g ) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These compositions are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.

标 题:Two powder synthesis of hydrotalcite and hydrotalcite-like compounds with divalent inorganic anions

权利人:ALUMINUM CO OF AMERICA
摘要:There is provided a method for making a divalent inorganic anion-intercalated hydrotalcite-like material by first reacting a magnesium-containing powder and a transition alumina powder in a carboxylic acid-free aqueous suspension to form a meixnerite intermediate. This intermediate is then contacted with a divalent inorganic anion, in its acid, acid salt or ammonium salt form, to make a hydrotalcite-like material. The latter is then separated from the suspension. Representative materials include a sulfate- and metavanadate-intercalated hydrotalcite-like material.

摘要:The present invention provides a series of ionic vinyl covalent organic framework materials constructed in two ways by means of designing a novel method. Such materials feature high crystallinity and specific surface area, cost-efficiency, simple synthesis, capability of self-forming and mass production, and the like. The synthesis process avoids the use of organic solvents and thus the risks of high pressure during the reaction process, and thereby possesses suitability for mass production and industrial potential. In addition, the ionic COF materials have the capability of efficiently isolating oxygen-containing anions from water, and have great industrial application prospects.

摘要:Novel powder coating compositions containing reactive hyperbranched polymers are disclosed and claimed. Preferred embodiments include powder coating compositions formed from hyperbranched polyesters having terminal hydroxy, carboxy, epoxy, and isocyanate groups. Preferred hyperbranched polyesters are formed from alpha , alpha -bis-(hydroxymethyl)-propionic acid, which act either as crosslinkers, adhesion promotors, or flow and leveling agents. A process for the synthesis of powder coating compositions is also disclosed which involves (a) self condensation of one or more of the multifunctional monomers to form the hyperbranched polymer, optionally, in the presence of suitable reactive end-capping moieties which are described herein; (b) melt blending of the hyperbranched polymer with suitable amounts of one or more of polyesters, epoxy resins, blocked urethane resins, or acrylic resins, a crosslinker, and one or more of suitable additional ingredients including degassers or flow and leveling agents, to form a flake; and (c) grinding and sieving of the flake to form the powder coating composition. These compositions exhibit improved flow and curing properties. These compositions can therefore be formed into thin films and can be cured at low temperatures to form smooth surfaces. Additionally, these films are hard and exhibit enhanced impact resistance properties than the conventional polyester resins. Thus, these powder coating compositions find utilities in automotive, packaging, and appliances.
