摘要： The present invention provides a curable composition that comprises a polymer (A) containing a cross-linkable silyl group and a condensation catalyst (B). The polymer (A) containing a cross-linkable silyl group is obtained by a process comprising the steps of conducting a radical polymerizable monomer in the presence of a thiocarbonylthio compound. For example, the polymer (A) is obtained by (i) initiating a reversible addition-fragmentation chain transfer polymerization of a radical polymerizable monomer in the presence of a thiocarbonylthio compound, and (ii) adding an unsaturated compound containing a cross-linkable silyl group for copolymerization when a consumed amount of the radical polymerizable monomer by the polymerization has reached a level of 80% or more.
