PROBLEM TO BE SOLVED: To provide a modified product of a polyorganosiloxane having high heat resistance, high light resistance, excellent cold shock resistance, and a higher gas-barrier property; a composition containing the modified product; and a cured product of the composition.SOLUTION: Provided is a modified product of polyorganosiloxane, which is a hydrosilylation reaction product of a silane compound having, in a molecule, at least one carbon-carbon double bond having reactivity with an SiH group; a linear and/or cyclic polyorganosiloxane compound having, in a molecule, at least two SiH groups; and a silane compound having, in a molecule, one carbon-carbon double bond having reactivity with an SiH. Also provided are a composition containing the modified product and a cured product of the composition. |
