Abstract
A modified polymer is produced by reacting (A) a polymer with (B) a compound having a nitroxide free radical in the molecule stable at room temperature and in the presence of oxygen, (C) an organic peroxide, and (D) a radically polymerizable monomer having a functional group in the presence of (E) an amine compound comprising a monoamine compound represented by the general formula: NRRR(R: C-Calkyl group or aryl group; Rand R: H, C-Calkyl group, or aryl group) or a polyamine compound represented by the general formula: (R)N(RN)RN(R)(R: H or C-Calkyl group; Rand R: C-Calkylene group; n: 0 to 20). This method can not only reduce the reaction temperature but also improve the modification rate.
