摘要:A method of preparing a composition including crystalline particles of a halide perovskite, a composition and a perovskite-based device including the same. The halide perovskite has a chemical formula ABX3, wherein A is a monocation, B is selected from a combination of lead (II) and a dopant and X is selected from a halide.

标 题 :Polymerization of olefins
发明人：BROOKHART MAURICE S; JOHNSON LYNDA KAYE; KILLIAN CHRISTOPHER MOORE
权利人:DU PONT
摘要:Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear α-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected α-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected α-diimine nickel complexes with ethylene.

摘要:A composition containing unique particles of copper pyrithione wherein greater than 20 wt % to 90 wt % of the particles have a particle size of greater than 10 microns, as determined by laser light scattering using a particle size distribution analyzer, and wherein the particles are flat acicular needle-shaped is described herein. Also described herein is an antifouling paint containing the copper pyrithione and a method of making the composition and antifouling paint.

标 题 :Latex compositions containing ethylenically unsaturated esters of fatty compounds and applications thereof
发明人：THAMES SHELBY FRELAND; PANJNANI KAMLESH GOPICHAND; FRUCHEY OLAN STANLEY
权利人:UNIV SOUTHERN MISSISSIPPI
摘要:Novel latex or emulsion compositions containing internally plasticizing and crosslinkable monomers derived from traditional semi-drying or non-drying oils are disclosed and claimed. The monomers are ethylenically unsaturated derivatives of long-chain olefinic compounds. Preferred embodiments include latex formed from acrylate or methacrylate esters of fatty alcohols. A process for the synthesis of the latex composition is also disclosed, which involves (a) polymerization of the ethylenically unsaturated derivatives of a long-chain olefinic compound 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 (Tg) 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.

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:Synthesis of zinc acrylate copolymer from acid functional copolymer, zinc pyrithione, and copper compound
发明人：KAPPOCK PAUL S; TAKAHASHI KAZUNOBU
权利人:ARCH CHEM INC
摘要:Disclosed is a composition containing zinc ester functional polymer and particulate copper pyrithione, wherein the particles have an average aspect ratio within a range of from about 8 to about 15, where the zinc ester functional polymer and the copper pyrithione are obtained by reacting an acid functional polymer with zinc pyrithione and a copper salt or a copper carboxylate. Also disclosed is an antifouling coating containing such a composition.
