    • A preparation process of a polymer comprising conducting ring-opening polymerization of a 4- to 10-membered ring-opening polymerizable cyclic monomer in the presence of a phosphazenium salt of an active hydrogen compound represented by the chemical formula (1): ##STR1## wherein n is an integer of 1 to 8 and indicates the number of phosphazenium cations, Z.sup.n- is an anion of a n-valent active hydrogen compound derived by releasing n protons from an active hydrogen compound having a maximum of 8 active hydrogen atoms, a, b, c and d are individually a positive integer or 0 and are not all 0 at the same time, R's are the same or different hydrocarbons having 1 to 10 carbon atoms, and two R's located on each common nitrogen atom may be coupled together to form a ring structure; or in the presence of the phosphazenium salt of the active hydrogen compound and the active hydrogen compound is disclosed. The process can prepare polymer by ring-opening polymerization of a 4- to 10-membered ring-opening polymerizable cyclic monomer in the presence of an initiator which causes no specific problem or preparation and handling, contains quite no installic ingredient and has no residual odor.
