PROBLEM TO BE SOLVED: To provide a process for producing a resin composition which enables a resin composition composed of a block copolymer to be efficiently produced, and to provide the resin composition having various excellent characteristics.SOLUTION: A process for producing a resin composition of the present invention is a process which uses a microreactor system, comprising: a first step of mixing a first liquid containing monomer A having a norbornene skeleton and a second liquid containing a polymerization initiator to obtain a third liquid containing polymer A obtained by polymerization of the monomer A; and a second step of mixing a fourth liquid containing a monomer B having a norbornene skeleton and the third liquid, to polymerize the monomer B onto a growth terminal of the polymer A, thereby obtaining a block copolymer. When, in polymerization conditions of the second step, a rate of polymerization of the monomer A and a rate of polymerization of the monomer B are denoted by Xabd X, respectively, a relationship of X≥10Xis satisfied. |
