Abstract:
1. A method for producing a curable composition, the method comprising: polymerizing (A) a crosslinkable silyl group-containing organic polymer, wherein the polymer (A) is at least one selected from the group consisting of a crosslinkable silyl group-containing polyoxyalkylene polymer, a crosslinkable silyl group-containing (meth)acrylic-modified polyoxyalkylene polymer, a crosslinkable silyl group-containing polyisobutylene polymer, and a first crosslinkable silyl group-containing (meth)acrylic polymer; preparing (B) a second (meth)acrylic polymer obtained by polymerizing a (meth)acrylic monomer having a polymerizable unsaturated bond in the presence of a metallocene compound represented by the following formula (1) and a crosslinkable silyl group-containing thiol compound, at least one end of the (meth)acrylic polymer being bonded to a residue, —S—R3 (where R3 represents a group having a crosslinkable silyl group) obtained by removing a hydrogen atom from the crosslinkable silyl group-containing thiol compound; and blending said polymer (A) and said second (meth)acrylic polymer (B): wherein M represents a metal selected from the group consisting of metals of Groups 4, 5, and 14 of the periodic table, chromium, ruthenium, and palladium; R
