<P>PROBLEM TO BE SOLVED: To provide a method for producing a polycondensation resin using an aromatic monomer or an alicyclic monomer. <P>SOLUTION: In the method for producing a polycondensation resin, a homogeneous polycondensation resin with molecular weight distribution of 1.8 or less is obtained by performing melt polycondensation using an aromatic monomer or an alicyclic monomer under atmosphere of subcritical carbon dioxide or supercritical carbon dioxide. <P>COPYRIGHT: (C)2013,JPO&INPIT |
