    摘要: 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: NR1R2R3 (R1: C1-C20 alkyl group or aryl group; R2 and R3: H, C1-C20 alkyl group, or aryl group) or a polyamine compound represented by the general formula: (R4)2N(R5N)nR6N(R4)2 (R4: H or C1-C6 alkyl group; R5 and R6: C1-C6 alkylene group; n: 0 to 20). This method can not only reduce the reaction temperature but also improve the modification rate.
