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.

标题 :Fluorinated elastomers with low glass transition temperatures based on vinylidene fluoride and free of tetrafluoroethylene or siloxane group
发明人:AMEDURI BRUNO M; ARMAND MICHEL; BOUCHER MARIO; BOUTEVIN BERNARD L
权利人:HYDRO QUEBEC
摘要:The present invention describes synthesis of new fluorinated elastomers presenting very low glass transition temperatures, a good resistance to bases, petroleum and fuels and good properties for forming. These elastomers contain, by way of example, from 90 to 50 mole % of vinylidene fluoride (VDF) and from 10 to 50 molar % of perfluoromethyl vinyl ether (PMVE). In this precise case, they are prepared by radical copolymerisation of VDF and with PMVE in presence of various organic initiators such as for example the peroxides, the peresters or the diazo compounds.

标 题 :Process for the dimerization of hexafluoropropene oxide
发明人:KUEHNE GERHARD
权利人:HOECHST AG
摘要:In the dimerization of hexafluoropropene oxide to give oligomeric acid fluorides of the formula the ratio of the oligomeric constituents formed is directed, in an improved manner, towards the formation of the dimer (n=0) if the reaction is carried out in the presence of a catalyst system which consists of a mixture of a copper (I) compound and a copper (II) compound mixed with a complex-forming agent from the group of the nitriles, isocyanides, tertiary phosphines and cyclic hydrocarbons with 6 to 12 ring atoms and 2 to 3 double bonds in the ring, and an aprotic organic solvent. The dimer is an intermediate product in the synthesis of perfluoropropyl perfluorovinyl ether, the latter being employed as a comonomer in fluorine-containing copolymers.

标题:Fluorosulphonated elastomers with low glass transition based of vinylidene fluoride
发明人:AMEDURI BRUNO MICHEL; ARMAND MICHEL; BOUCHER MARIO; MANSERI ABDELLATIF
权利人:HYDRO QUEBEC
摘要:The present invention describes the synthesis of new sulforated fluorinated elastomers having very low glass transition temperatures (Tg), a good resistance to bases, oils and fuels and good properties of workability. These elastomers contain, by way of example, from 80 to 60 mole % of vinylidene fluoride (VDF) and 20 to 40 mole % of perfluoro(4-methyl-3,6-dioxaoct-7-ene) sulfonyl fluoride (PFSO2F). In this case, they are prepared by radical copolymerisation of VDF and PFSO2F in the presence of different organic initiators, for example, peroxides, peresters or diazo compounds.
