| titleOfInvention | Method for producing polyester resin or composition thereof |
| abstract | (57) [Summary] [Purpose] The amount of decomposed gas generated is small when used at high temperatures. Also provided is a method for producing a modified polyester having a small amount of sublimate when melted or a composition thereof. [Structure] When a polyester is produced from an acid component mainly composed of a difunctional aromatic carboxylic acid or a lower alcohol ester thereof and a diol component, at any time from the monomer preparation step to the completion of the polycondensation reaction, or At least one aromatic sulfonic acid compound represented by the following general formula (I) is added to the polyester after polycondensation in an amount of 0.005 to 2 mol% based on the repeating ester unit of the produced polyester. [Chemical 1] (However, Ar is a benzene ring or a naphthalene ring. N Is an integer of 1 to 10. m 1 and m 2 are each an integer of 1 to 2. X is a group selected from alkylene having 2 or 3 carbon atoms, and when n or m 1 is 2 or more, X may be the same or different. Y is an alkyl group or an alkylidene group, which may be the same or different. ) |
