Examples
Example Embodiment
[0027] Example 1
[0028] After the 2 liter high-pressure reactor with electromagnetic stirring is deoxidized, 1000g of high-purity water, 100g of diisopropyl ether, 0.4g of isobutyl peroxydicarbonate and 0.6g of N,N-dimethylaniline are added, and the stirring rate is 400rmp. Bottom, filled with 100g of chlorotrifluoroethylene, reacted at 30°C for 4 hours, adjusted the stirring rate to 100rmp, and heated to 50°C. Continue the reaction for 2 hours. Open the reactor and, while stirring, wash the obtained resin with distilled water at 80°C and then with distilled water at room temperature. Finally, it was dried at 170°C for 12 hours to obtain a polychlorotrifluoroethylene resin in the form of beads with a diameter of 1 mm to 3 mm.
Example Embodiment
[0029] Example 2
[0030] Except that the added amount of diisopropyl ether is 150 g, the rest is the same as in Example 1, and the polymerization reaction is performed to obtain a polychlorotrifluoroethylene resin in the form of beads of 1 mm to 3 mm.
Example Embodiment
[0031] Example 3
[0032] Use n-hexane instead of diisopropyl ether, add 150g, and use dibenzoyl peroxide instead of isobutyl peroxide. The same polymerization reaction as in Example 1 is carried out to obtain beads of 0.8mm-3mm. Fluorochloroethylene resin.
