The objective of the present invention is to provide a derivative of polybutadiene suitable as a material of a curable composition for obtaining a cured product having high shearing stress. The present invention provides: a silylated polybutadiene characterized by containing a repeating unit represented by formula (I) (in the formula: R1, R2, and R3 each independently represents an unsubstituted or substituted aryl group, an alkyl group, or an aralkyl group. Among R1 to R3, at least one of R1 to R3 is an aryl group or aralkyl group.); a curable composition characterized by containing the silylated polybutadiene and a polymerization initiator; and a cured product obtained by curing the curable composition.
本发明的目的是提供一种聚丁二烯衍生物,该衍生物适合用作固化组合物的材料,以获得具有高剪切应力的固化产品。本发明提供了:一种硅烷化聚丁二烯,其特征在于含有由式(I)代表的重复单元(式中:R1、R2 和 R3 各自独立地代表未取代或取代的芳基、烷基或芳烷基。在 R1 至 R3 中,至少有一个 R1 至 R3 是芳基或烷基);固化组合物,其特征是含有硅烷化聚丁二烯和聚合引发剂;以及通过固化该固化组合物得到的固化产物。
