Abstract
A curable resin composition comprising (A) 100 parts by weight of an elastomeric organic polymer of a saturated hydrocarbon having at least one silicon-containing group cross-linkable by the formation of a siloxane bond at the molecular ends, and (B) 0.01 to 10 parts by weight of a sulfur-containing antioxidant. The curable resin composition produces a cured product having excellent heat resistance.
