    Abstract: PROBLEM TO BE SOLVED: To provide a catalyst which is suitable for the reaction of a carboxylic ester with an alkylene oxide and enables to produce a desired alkylpolyalkylene glycol carboxylate under a mild reaction condition without any undesirable byproduct formed. SOLUTION: The alkylpolyalkylene glycol carboxylate can be produced by a method comprising a process for reacting a carboxylic ester with an alkylene oxide in the presence of a multimetal cyanide compound as a catalyst represented by formula (I): M 2 M a [M (CN)b (A)c ]d fM g Xn mM p Yq h(H2 O)eLkP, for example, by formula (II): M Fe[Fe(CN)6 ]nH2 O [wherein M is a potassium ion (K ) or an ammonium ion (NH4 )]; and can be used as a raw material for a concrete fluidizing polymer.

    Abstract: The present invention relates to a process for reacting epoxides with an initiator compound in the presence of a double metal cyanide compound as a catalyst, said process having a shortened induction period, and the double metal cyanide compound being activated by adding the epoxide to a mixture of double metal cyanide compound and initiator compound at an internal reactor pressure of less than 1 bar, and also to the polyethers themselves obtainable by such a process.
