Abstract
PURPOSE:To obtain the titled polymer having excellent first discoloration, transparency and heat-resistance, by dispersing a post-chlorinated vinyl chloride polymer in an aqueous medium in the form of a slurry and treating the polymer with nitrilotriacetic acid mixed to the slurry. CONSTITUTION:A post-chlorinated vinyl chloride polymer produced by the post-chlorination of a vinyl chloride polymer is dispersed in an aqueous medium (e.g. methyl alcohol or acetone) in slurry state, mixed with usually 100-5,000ppm of nitrilotriacetic acid of formula (based on the weight of the post-chlorinated vinyl chloride polymer) and stirred preferably at 40-70 deg.C for 20-100min to effect post-treatment. The post-chlorination reaction of the vinyl chloride polymer can be achieved preferably by dispersing said polymer in an aqueous medium in slurry state and carrying out a photo-chemical reaction in wet or dry state under the supply of excess chlorine gas and light irradiation with a light source such as a mercury lamp or an arc light.
