Abstract
Abstract Curable compsn. which gives a cured article improved in restorability, comprises oxypropylene polymer having gp(s) contg. a silicon atom having a hydroxyl or hydrolysable gp. bonded thereto, on Mw/Mn of 1.6 or less, and a number-average mol. wt. of 6,000 or above, salt of an organotin (11) carboxylic acid, and an organic amine cpd.
