Title:
ポリマー溶液の脱溶媒方法、ポリマーの製造方法及び脱溶媒装置
Document Type and Number:
Japanese Patent JP3817564
Kind Code:
B2
Abstract:
The invention relates to a method for removing solvent from polymer solution generated by solution polymerization and an apparatus for removing solvent from such polymer solution. The method for removing solvent from polymer solution in accordance with the invention is a method for removing solvent by putting polymer solution and steam in contact with each other to remove the solvent by steam stripping, including a step of feeding a part of the steam into tube 2 for transferring polymer solution to tank 1 for removing solvent, and a step of feeding the remaining part of the steam into the inside of the tank for removing solvent. Particularly, the amount of the steam to be fed into the tube is preferably at 10 to 90 % by mass, when the whole amount of the steam is defined as 100 % by mass. The polymer contained in the polymer solution includes various polymers such as butadiene rubber, styrene • butadiene rubber, and ethylene • alpha -olefin • non-conjugated diene copolymer rubber. Further, the solvent is preferably n-hexane, n-pentane, cyclohexane, toluene and the like.
