ABSTRACT:
The present invention has its object to provide a transparent curable composition which may be prepared as a one package formulation, and which is excellent in strength, elongation at break, weather resistance, and adhesiveness of the resultant cured product.In addition, the present invention provides a curable composition which comprises 100 parts by weight of a vinyl polymer (I) the main chain of which is the product of living radical polymerization and which contains a crosslinkable silyl group, and 1 to 200 parts by weight of a micronized hydrophobic silica (II). Furthermore, the present invention also provides a curable composition which comprises 100 parts by weight of a vinyl polymer (I) the main chain of which is the product of living radical polymerization and which contains at least one crosslinkable silyl group, and 1 to 200 parts by weight of a graft copolymer (III) obtained by graft polymerization of a crosslinkable rubber-like acrylic ester polymer and a vinyl monomer.
