| titleOfInvention | The manufacture method of chlorinated vinyl chloride-based resin |
| abstract | The invention provides heat endurance (initial coloring, heat-resistant stability) good and can obtain the manufacture method of the chlorinated vinyl chloride-based resin of transparent formed products. the manufacture method of chlorinated vinyl chloride-based resin of the present invention, in sealable reaction vessel, make vinyl chloride-based resin be suspended state with water and carry out thermal chlorination when reaction, more than the aqueous suspension of vinyl chloride-based resin powder is warming up to 85 DEG C by limit and lower than the predetermined temperature in the temperature range of 95 DEG C, the 1st thermal chlorination reaction is carried out on limit, and, under this predetermined temperature, carry out afterwards the 2nd thermal chlorination reaction, in this manufacture method, at 55～70 DEG C of aqueous suspension temperature, chlorine is imported in reaction vessel and start thermal chlorination reaction, under the state of the temperature below the glass transition temperature that the temperature in reaction vessel is remained on to the chlorinated vinyl chloride-based resin in reaction vessel, be warming up to this predetermined temperature, so that the chlorine containing ratio of the chlorinated vinyl chloride-based resin in reaction vessel reaches 58 % by weight above and carry out the 1st thermal chlorination reaction lower than the mode of 60 % by weight, afterwards, under this predetermined temperature, carry out the 2nd thermal chlorination reaction. |
