Abstract
The present invention has an object of producing a polyoxyalkylene compound by ring-opening polymerization of an alkylene oxide to a certain specific highly hydrophobic initiator. The present invention provides a process for producing a polyoxyalkylene compound, characterized in that the polyoxyalkylene compound is produced by ring-opening polymerization of an alkylene oxide, in the presence of a plural metal cyanide complex catalyst, with an initiator selected from an organopolysiloxane compound having an active hydrogen-containing functional group to which an alkylene oxide is reactive, and a fluorine-containing compound having such an active hydrogen-containing functional group and a fluorinated hydrocarbon group.

A process for producing a polyoxyalkylene compound, comprising ring-opening polymerizing an alkylene oxide, in the presence of a plural metal cyanide complex catalyst, with an initiator selected from the group consisting of an organopolysiloxane compound, wherein said organopolysiloxane compound is a polymer of a siloxane having at least one organic group bonded thereto and wherein at least one of said organic groups is an organic group having an active hydrogen-containing functional group, and a fluorine-containing compound selected from the group consisting of a compound of one of the following chemical formulae (4) to (8):
- R.sub.f.sup.1 --R.sup.11 --X.sup.2 (4),
- R.sub.f.sup.1 --COOX.sup.3 ( 5),
