| titleOfInvention | Method for producing polymer by solid phase polymerization |
| abstract | In solid phase polymerization of a polymer, it is difficult to maintain the fluidity of the raw material layer due to an increase in the powder pressure at the lower part of the raw material layer and the volume expansion of the raw material layer itself, which hinders stable continuous production. ing. Further, the degree of polymerization caused by uneven temperature distribution in the polymerization tank is also a problem in terms of stable production of the product and product quality. Prevents the polymer in the raw material layer from consolidating and fusing, and further uniforms the temperature distribution in the raw material layer to eliminate unevenness in the degree of polymerization of the product. I will provide a. In solid phase polymerization of a polymer, the solidification or fusion of the polymer in the lower part of the raw material layer is reduced by controlling the powder pressure of the polymer in the lower part of the raw material layer to a certain value or less, and stable production. And a method for producing a quality polymer of the product. [Selection] Figure 1 |
