摘要:The present invention relates to an arylphenoxy catalyst system producing an ethylene homopolymer or copolymers of ethylene and α-olefins, and a method of producing an ethylene homopolymer or copolymers of ethylene and α-olefins having a high molecular weight under a high temperature solution polymerization condition using the same. The catalyst system includes a group IV arylphenoxy-based transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst. In the transition metal catalyst, a cyclopentadiene derivative and arylphenoxide as fixed ligands are located around the group IV transition metal, arylphenoxide is substituted with at least one aryl derivative and is located at the ortho position thereof, and the ligands are not crosslinked to each other. The catalyst includes an environmentally-friendly raw material, synthesis of the catalyst is economical, and thermal stability of the catalyst is excellent. It is useful for producing an ethylene homopolymer or copolymers of ethylene and α-olefins having various physical properties in commercial polymerization processes.

标 题 :Chlorination of difluoromethyl methyl ether
发明人：O'NEILL GERALD J; BULKA ROBERT J
权利人:HAMPSHIRE CHEMICAL CORP
摘要:The synthesis of fluorinated dimethyl ethers of the formula CF 2 HOCCl x F y H 3- (x+y) wherein x is 0, 1 or 2; y is 1, 2 or 3; and wherein (x+y) is 1, 2 or 3. The process involves chlorination of methyl difluoromethyl ether in the presence of a solvent to form a chlorinated reaction product of the formula CF 2 HOCH 3-z Cl z wherein z is 1, 2 or 3. The process may also be carried out in the presence of oxygen in order to inhibit the formation of CF 2 HOCCl 3 . The resulting compound(s) is then fluorinated with HF before or after separation, to give a fluorinated reaction product including the aforementioned fluorinated dimethyl ethers.
