| titleOfInvention | Polyester resin and method for producing the same |
| abstract | [Objective] Polyester resin polycondensed in the presence of a titanium compound, with reduced amount of terminal carboxyl groups, and by-products such as oligomers and cyclic trimers due to solid-phase polycondensation can be reduced. The present invention also provides a polyester resin having good physical properties such as color tone and transparency, and a method for producing the polyester resin at a high solid-phase polycondensation rate. [Constitution] A dicarboxylic acid component containing terephthalic acid as a main component and a diol component containing ethylene glycol as a main component are subjected to an esterification reaction, and (1) selected from the group consisting of titanium group elements of Group 4A of the periodic table A polyester resin obtained by polycondensation in the presence of at least one elemental compound, (2) a calcium compound, and (3) a phosphorus compound, and having a terminal carboxyl group amount of 40 equivalents / ton of resin or less, And a method for producing the polyester resin. [Selection figure] None. |
