Objects of the present invention are to provide a process for easily producing an alkenyl-terminated vinyl polymer without using a metal compound requiring a complicated purification step, and to provide a curable composition containing the vinyl polymer.
An alkenyl group is incorporated into an end of a vinyl polymer having a thiocarbonylthio structure at the end to produce an alkenyl-terminated vinyl polymer. Mixing this vinyl polymer with a compound having a hydrogen-silicon bond and a hydrosilylation catalyst gives the curable composition.
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.
