PROCESS FOR PRODUCING RADICAL POLYMER AND MICROAPPARATUS FOR CHEMICAL REACTION

摘要

A process for efficiently producing in a short time a radical polymer having a regulated molecular-weight distribution or a narrow molecular-weight distribution by the free-radical polymerization of a radical-polymerizable monomer; and a microapparatus for chemical reactions which can be easily manufactured. The process for radical polymer production comprises introducing a free-radical polymerization initiator and a radical-polymerizable monomer into reaction tubes having an inner diameter of 2 mm or smaller and polymerizing the monomer in a homogeneous liquid state while causing the monomer to flow through the reaction tubes. The microapparatus for chemical reactions comprises a jacket through which a temperature-regulating fluid can be passed and two or more cylindrical tubes which have been disposed in parallel within the jacket and each has an inner diameter of 2 mm or smaller. By passing a temperature-regulating fluid through the jacket, the reaction temperature in the cylindrical tubes can be regulated.
