Process for producing radical polymer and microapparatus for chemical reaction

Abstract

The present invention provides a method for producing a radical polymer having controlled molecular weight distribution or a narrow molecular weight distribution profile, comprising feeding a radical polymerization initiator and a radical-polymerizable monomer into a reaction tube having an inner diameter of 2 mm or less and performing polymerization in the reaction tube in a homogeneous liquid state under flow conditions. Also provided is a microreactor having a jacket for allowing a temperature-regulating fluid to pass therethrough and a plurality of round tubes which are arranged in parallel in the jacket, each having an inner diameter of 2 mm or less, wherein reaction temperature in the round tubes can be regulated through flowing of the temperature-regulating fluid in the jacket.
