The present invention provides a composition for on-site forming gaskets, which has excellent heat resistance, weather resistance, oil resistance, curability, compression set, and the like, a gasket, and (meth)acrylic acid and a curable composition thereof. Specifically, the present invention provides a composition for on-site forming gaskets containing a vinyl polymer with a (meth)acryloyl group at a molecular end as an essential component, and a gasket, a cured product of the composition exhibiting predetermined compression set. Also, the present invention provides a (meth)acrylic polymer having a (meth)acryloyl group at a molecular end and a curable composition thereof, a cured product exhibiting high oil resistance.
