ABSTRACT:
A polymer of an epoxy compound is selectively obtained by polymerizing an epoxy compound having the formula (I): ##STR1## wherein R is a substituted or unsubstituted alkyl group, by using an initiator comprising a silyl ether represented by the general formul (II): ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are each a substituted or unsubstituted alkyl or aryl group, in the presence of an inorganic fluoride catalyst, thereby preparing a polyether having a silyloxy group in its terminal.
