The resin is made by chlorination modification of polyvinyl chloride (PVC) resin and is a new type of engineering plastic. The product is white or light yellow, tasteless, odorless, non-toxic loose particles or powder. After chlorination of PVC resin, the irregularity of molecular bonds increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the material's heat resistance, acid, alkali, salt, oxidant corrosion resistance, etc. The mechanical properties of the heat deformation temperature of the resin are improved, the chlorine content is increased from 56.7% to 63-69%, and the Vicat softening temperature is increased from 72-82℃ to 90-125℃.
