<p>The present invention aims to improve storage stability of an oxyalkylene polymer (P) wherein a reactive silicon group is bonded to a polyoxyalkylene chain through a urethane bond. Specifically, an oxyalkylene polymer (P) is produced by subjecting a hydroxy group-containing polymer (pP) having a polyoxyalkylene chain and a hydroxy group and an isocyanate group-containing compound (U) represented by the general formula (1) below to a urethanization reaction in the presence of an iron catalyst (S) composed of iron naphthenate and/or iron octoate. (Si(-X1)a(-R1)3-a)-Q1-NCO (1) In the formula, X1 represents an alkoxy group having 1-6 carbon atoms; R1 represents an optionally substituted monovalent organic group having 1-20 carbon atoms; Q1 represents a divalent organic group having 1-20 carbon atoms; and a represents an integer of 1-3.</p> |
