| titleOfInvention | Method for producing copolyester by solid phase polymerization |
| abstract | The present invention relates to a method for producing a copolyester by using a solid phase polymerization method, comprising a esterification reaction and a polycondensation reaction of a dicarboxylic acid component containing terephthalic acid and a diol component containing 1,4-cyclohexanedimethanol. To obtain a copolyester prepolymer, which is characterized by crystallization and solid phase polymerization.n n n According to the present invention, by using a copolyester resin containing 50 to 100 mol% of 1,4-cyclohexanedimethanol based on the dicarboxylic acid component of the polyester, By performing the polymerization in two stages, it is possible to produce a crystallized chip state like the existing polyethylene terephthalate. That is, since there is no risk of fusion in the dryer during drying, drying is possible at a temperature higher than the glass transition temperature, and thus drying is possible within a short time under the desired moisture content, thereby obtaining a product having time and economic advantages in the process. .n n n 1,4-cyclohexanedimethanol, polyester, ethylene glycol, terephthalic acid, drying method, crystallization, solid state polymerization |
