    Abstract: Provided is a curable composition that, while reducing a used amount of (meth)acrylic acid ester monomers having a large number of carbon atoms, yields a cured product which has both good transparency and good elongation. The curable composition contains (A) a silyl group-containing (meth)acrylic-based polymer, (B) a silyl group-containing polyoxyalkylene-based polymer having a number average molecular weight of 20,000 or more, and (C) an aromatic ring-containing plasticizer. Units derived from CH2═C(R1)(COOR2), where R1 is a hydrogen atom or a methyl group, and R2 is a group having nine or more carbon atoms, account for 5% by weight or less of all structural units of (A). The curable composition contains 60 parts by weight or more of (C) with respect to 100 total parts by weight of (A) and (B), and a cured product has a haze of 55 or less, the haze being obtained through a curing test.

    Abstract: Provided is a curable composition which is free of organotin compounds to be environmentally friendly and whose cured product shows high elongation and high elastic recovery to be suitable particularly as a sealant. The present invention relates to a curable composition containing a reactive silyl group-containing organic polymer (A) which has a highly active reactive silyl group at a molecular chain end, and a compound (B) having 2 to 10 ethyloxy groups in its molecule but having no amino group in its molecule, the compound (B) being a C1-C20 saturated hydrocarbon having one alkoxysilyl group, a C1-C20 hydrocarbon having two or more alkoxysilyl groups, or a C1-C20 polycarboxylic acid ester.

    Abstract: The present invention provides a sealant composition that includes a reactive silyl group-containing organic polymer, and gives a cured product having a low modulus and not having wrinkles or cracks on the surface even though the sealant includes as a curing catalyst a tetravalent tin compound, which is presumed to reduce recovery. The sealant composition is a one-component curable sealant composition including: a linear organic polymer (A) having a number average molecular weight of 11,000 to 30,000, and having an ethanol-elimination reactive silyl group at a molecular terminal; a tetravalent tin compound (B); and a plasticizer (C).
