PURPOSE:To obtain the composition excellent in tacking properties, deep curability and adhesion by compounding polyoxyalkylene polymer prepared by polymerization using a conjugate metal cyanide complex as a catalyst followed by the introduction of a silicon-containing hydrolyzable group, an air-setting compound and a photo-setting compound. CONSTITUTION:An organic polymer is prepared by polymerizing an alkylene oxide (e.g. propylene oxide) using a conjugate metal cyanide complex (e.g. zinc hexacyanocobaltate) as a catalyst to obtain a polyoxyalkylenediol having a number average molecular weight of >=5000 and introducing a silicon- containing group expressed by the formula [R<1> is 1-20C (substituted) monovalent hydrocarbon; X is hydrolyzable group; (a) is 1, 2 or 3[ at the ratio of >=0.3 per one molecule in terms of the average of the total molecules into the terminal of the obtained polyoxyalkylenediol. 100 pts.wt. of the prepared organic polymer is compounded with 0.01-20 pts.wt. of an air-setting compound (e.g. linseed oil) and/or 0.01-2 pts.wt. of a lightsetting compound (e.g. propyleneglycol dimethacrylate) to obtain the room temperature setting composition having a reduced tackiness on the surface of a cured body and excellent in softness, deep curability and adhesion. |
