摘要： The present disclosure relates to a process for the preparation of CPVC which includes reacting PVC with chlorine at a pre-determined temperature in the presence of at least one irradiation source having wavelength ranging from 254 and 530 nm while maintaining the radiant flux from 1.5 to 2 W/kg of PVC, irradiance at 0.13 W/cm2 and the number of photons emitted per second from 3×1018 to 5×1018, under agitation, for a time period ranging from 3 to 4 hours to obtain CPVC. The CPVC prepared from the afore-stated process has a whiteness index ranging from 89 to 96, a yellowness index ranging from 1.23 to 1.73 and stability ranging from 648 to 684 seconds. The rate of the chlorination reaction after employing the afore-stated process parameters ranges from 1.6 to 4.36 mole/hour/kg.

摘要： The present invention provides a method for removing unreacted monomer in polymer using a SCC comprising a housing having a rotation axis; a supply part of at least one polymer formed inside of the housing; at least two spinning cones that are installed so as to have a constant gradient from the upper part to the lower part to the rotation axis, move polymer supplied through the polymer supply part, and rotate around the rotation axis; a fixed cone that is fixed and formed on the inner side of the housing, and provides a pathway for sequentially moving polymer from a spinning cone at the upper part to a spinning cone at the lower part; a product collection part for collecting polymer moved through the spinning cone and the fixed cone; and a driving part for rotating the spinning cone. The method for removing unreacted monomers in polymer using SCC according to the present invention may control polymer residence time and thus does not lower polymer stability even under high temperature condition, and has high area density and thus has excellent unreacted monomer removal efficiency without using steam and the like, or with a small amount of steam, and the like.
