Process and apparatus for the preparation of polymer solution |
摘要 |
<p>A process for the preparation of a polymer solution comprises the steps of: mixing a polymer with a solvent to swell the polymer in the solvent; cooling the swelled mixture to a temperature of -100 to -10 DEG C; and then warming the cooled mixture to a temperature of 0 to 120 DEG C to dissolve the polymer in the solvent. According to the present invention, the swelled mixture is cooled at a rate of faster than 1 DEG C per minute, or the cooled mixture is warmed at a rate of faster than 1 DEG C per minute. Apparatuses for the preparation of a polymer solution are also disclosed. <IMAGE></p> |
