PVC STIRRED TANK REACTOR AND METHOD FOR PREPARING PVC RESIN USING THE SAME

摘要

More particularly, the present invention relates to a stirrer tank reactor including a two-stage impeller stirrer, wherein a reflux condenser is disposed at an upper portion of the stirring tank, (H / D) of the interval (h) between the lower end and the upper impeller of the two-stage impeller stirrer to the inner diameter (D) of the stirring tank is less than 0.65, and a stirring tank reactor using the same And a method for producing the PVC resin. According to the present invention, the mixing time of the upper mixture is lowered and the agitation force is increased, which has a favorable effect on the particle size distribution and the particle size of the polymer to be produced, and particularly, in the same polymerization reaction conditions, There is provided an agitating tank reactor capable of producing a polymer having a low specific gravity and a high plasticizer absorption rate and a method for producing a PVC resin using the same.
