    • 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.
    • 本发明提供一种包含含有可交联甲硅烷基的聚合物(A)和缩合催化剂(B)的固化性组合物。 含有可交联甲硅烷基的聚合物(A)通过包括以下步骤的方法获得:在硫代羰基硫代化合物的存在下进行自由基聚合单体。 例如,聚合物(A)通过(i)在硫代羰基硫代化合物的存在下引发可自由基聚合的单体的可逆加成 - 断裂链转移聚合而获得,和(ii)加入含有可交联甲硅烷基 当通过聚合反应的自由基聚合性单体的消耗量达到80%以上时,进行共聚。
