  Improved double metal cyanide catalysts are disclosed. The substantially amorphous catalysts of the invention are more active for polymerizing epoxides than conventional DMC catalysts, which have a substantial crystalline component. Polyol products made with the catalysts are unusually clear, have exceptionally low unsaturations, and contain no detectable amount of low molecular weight polyol impurities. A method of making the improved DMC catalysts, which involves intimately combining the reactants, is also disclosed.

  本发明揭示了改进的双金属氰化物催化剂。本发明的基本非晶态催化剂比具有相当晶体成分的传统DMC催化剂更活性，用该催化剂制备的聚醚醇产品异常清晰，具有异常低的不饱和度，并且不含可检测到的低分子量聚醇杂质。本发明还揭示了一种制备改进的DMC催化剂的方法，该方法涉及密切组合反应物。

  Improved double metal cyanide (DMC) catalysts useful for making epoxide polymers are disclosed. One catalyst is a paste of a double metal cyanide (DMC) compound, an organic complexing agent, and water. The paste comprises at least about 90 wt. % of particles having a particle size within the range of about 0.1 to about 10 microns as measured by light scattering in polyether polyol dispersions of the catalyst particles. Preferred catalysts have a bimodal particle size distribution. The paste catalyst is more active and simpler to prepare than powder DMC catalysts. Polyols made from the paste catalyst have low unsaturations, low viscosities, and narrow molecular weight distributions, and are useful in making a variety of polyurethane products.

  本发明公开了用于制造环氧聚合物的改进型双金属氰化物（DMC）催化剂。其中一种催化剂是由双金属氰化物（DMC）化合物、有机络合剂和水组成的浆糊。该浆糊包含至少约90重量％的粒子，其粒径在约0.1至约10微米之间，通过在催化剂粒子的聚醚多元醇分散体系中进行光散射测量得出。首选催化剂具有双峰粒径分布。与粉末DMC催化剂相比，浆糊催化剂更活性且制备更简单。使用浆糊催化剂制备的聚醇具有低不饱和度、低粘度和窄分子量分布，可用于制造各种聚氨酯产品。

Polyol products made with the catalysts are unusually clear, have exceptionally low unsaturations, and contain no detectable amount of low molecular weight polyol impurities. Methods of making the improved DMC catalysts are also disclosed. In one method, the reactants are intimately combined to produce a catalyst of the invention. In another method, an organic complexing agent is initially present in the reactant solutions.

  Polyoxyalkylene polyols containing double metal cyanide complexes or residues thereof as are produced during the preparation of polyoxyalkylene polyols by the double metal cyanide complex catalyzed oxyalkylation of a suitably functional hydric initiator are stable without catalyst removal. Isocyanate-terminated prepolymers prepared from such polyols are surprisingly viscosity-stable relative to similar prepolymers prepared from polyols not containing double metal cyanide complexes or residues thereof.
