Abstract
A process for producing a modified polymer having, in the molecule thereof, an organic group(s) introduced thereinto and derived from a compound(s) having a free radical comprising reacting a polymer such as an elastomer with a compound having the free radical stable at an ordinary temperature in the presence of oxygen, after or while a carbon radical(s) is generated in the polymer, whereby the modified polymer having an improved bondability and processability is formed.

1-5. (canceled)
A modified polymer comprising an organic group derived from a compound(s) having a mono-nitroxide free radical(s), wherein said modified polymer is obtained by (1) generating a carbon radical(s) in the molecule of a polymer to be modified by at least one means for generating a carbon radical selected from the group consisting of a radical initiator, electron beam, light and radiation, and (2) reacting the polymer having the carbon radical(s) generated above with a compound(s) having the mono-nitroxide free radical stable at an ordinary temperature in the presence of oxygen.
