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:The present invention is a process for obtaining a crystalline zinc borate having a particle size of 4 μm or less, the process comprising the steps of: mixing zinc borate and zinc oxide in a mixer to obtain zinc oxide with seed crystal; mixing solid and/or aqueous solution of boric acid, aqueous solution containing the dispersion agent and zinc oxide with seed crystal, and reacting them; pressing the product obtained as a result of the reaction to separate the product into two parts as a zinc borate SLUDGE and a reaction water rich in boric acid; transferring the reaction water rich in boric acid to a stock tank and keeping it in the heated stock tank; mixing zinc borate SLUDGE by transferring it to a washing unit and removing the non-reacted boric acid therein; transferring the mixture of zinc borate SLUDGE and the water to the filtering-pressing unit and pressing the same to separate it as SLUDGE and washing water; drying the separated SLUDGE in a dryer until the moisture ratio decreases below 1% and obtaining a crystalline zinc borate; transferring crystalline zinc borate to a cyclone to separate crystalline zinc borate according to the particle size; transferring the grains which have a particle size of 4 μm or less to a packaging unit; and reducing particle sizes of grains which have a particle size of more than 4 μm at a grinder, and transferring them to the packaging unit.

标 题 :Latex compositions containing ethylenically unsaturated esters of fatty compounds and applications thereof

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.
