It is an object of the present invention to provide a curable which has good storage stability and can give cured products retaining the high elongation characteristic originating from the polyether polymer and showing a high gel fraction and good weatherability.
Thus, the present invention provides a curable composition
which comprises the following two components:
a polyether polymer having at least one crosslinkable functional group and
a vinyl polymer
which is compatible with said polyether polymer having at least one crosslinkable functional group at a polymer terminus.
Further, the present invention provides a curable composition
which comprises the following three components:
a polyether polymer having at least one crosslinkable functional group,
a vinyl polymer incompatible with said polyether polymer and having at least one crosslinkable function group, and
a compatibilizing agent capable of compatibilizing said polyether polymer and said vinyl polymer with each other when added to a mixture thereof.
