Embodiment Construction

[0090] The supported catalysts of the present invention can be most broadly defined according to formula (I):

[0091] [DMCC]*b Supp (I)

[0092] in:

[0093] [DMCC] means a double metal cyanide complex comprising a double metal cyanide (DMC) compound, at least one organic complexing agent and a metal salt;

[0094] Supp means a hydrophobic carrier material; and

[0095] b represents the average weight ratio of the carrier material based on the total weight of [DMCC] and Supp, and is preferably in the range of 1% by weight≤b≤99% by weight, more preferably in the range of 10% by weight≤b≤70% by weight range,

[0096] Wherein the hydrophobic carrier material is selected from hydrophobic materials characterized by a methanol wettability value of at least 30% by volume as determined by the methanol wettability test described in the specification; carbonaceous inorganic solid materials; or combined with carbon, etc. Electronic inorganic solid materials.

[0097] The average weig...

Abstract

The present invention is directed to supported catalyst having utility in the polymerization and co-polymerization of epoxide monomers, the supported catalyst having the general Formula (I): [DMCC] *b Supp, wherein: [DMCC] denotes a double metal cyanide complex which comprises a double metal cyanide (DMC) compound, at least one organic complexing agent and a metal salt; Supp denotes a hydrophobicsupport material; and b represents the average proportion by weight of the support material, based on the total weight of [DMCC] and Supp, and is preferably in the range 1 wt.% <= b <= 99 wt.%.

Description

technical field [0001] The present invention relates to double metal cyanide (DMC) compounds useful as catalysts in polymer synthesis. More particularly, the present invention relates to providing double metal cyanide (DMC) compounds on hydrophobic support materials that are effective as catalysts for the ring-opening polymerization of epoxide monomers. Background technique [0002] Usually contains zinc hexacyanocobaltate (Zn 3 [Co(CN) 6 ] 2 ) double metal cyanide (DMC) compounds are known in the art as catalysts for the ring-opening polymerization of epoxides to produce polyethers. Compared to polymers obtained using basic catalysts, DMC catalysts provide polyethers characterized by a narrow molecular weight distribution, high average molar mass and a very low number of double bonds at the polymer chain ends. Alternatively, DMC catalysts can also be used to react the epoxide with CO 2 And polymerized with other suitable comonomers such as oxetanes, cyclic carbonates, ...
