METHOD FOR PRODUCING CURABLE POLYMER EXHIBITING EXCELLENT CURABILITY
摘要
<p>Disclosed is a method for producing a curable polymer whose cured product is excellent in hardness. Also disclosed is a curable composition. Specifically disclosed is a method for producing a curable polymer, which is characterized in that when a polymer (pP) having a polyoxyalkylene chain and a hydroxy group and a compound (U) having an alkoxysilyl group and an isocyanate group are urethanized, the polymer (pP) is urethanized while controlling the moisture content thereof to be 150 ppm or less, thereby producing an alkoxysilyl group-containing oxyalkylene polymer (P) having a urethane bond. Also specifically disclosed is a curable composition containing the thus-produced curable polymer.</p>
