A curable composition comprises (A) a polymer whose molecules have a main chain comprising carbon-carbon bonds and one or more isocyanatocarbonyl groups pendant to the main chain, the content of the isocyanatocarbonyl groups per polymer molecule being from 0.1 to 72.2% by weight, and (B) an active hydrogen atom-containing compound. Various polymers of the given type, including polymers having pendant isocyanatocarbonyl and/or isocyanato groups, are novel.
