Abstract: HYDROXYARYLPOLYMETHYLENESULFONIUM SALTS OF FORMULA 1, PREPARED BY CONDENSATION OF A PHENOL AND A POLYMETHYLENESULFIDE, CAN BE CONVERTED INTO A SULFONIUM HYDROXIDE INNER SALT II AND THEN THERMALLY POLYMERIZED TO YIELD POLYMERS CONTAINING A PLURALITY OF GROUPS OF FORMULA III:

(4-(HO-),R,R'',R"-PHENYL)-S+
(4-(-O+),R,R'',R"-PHENYL)-S
(-O-(R,R'',R"-PHENYLENE)-S-CH2-A-(B)N-CH2-) III

THESE POLYMERS AND COPOLYMERS ARE USEFUL WATER RESISTANT THERMOPLASTIC RESINS AND IMPREGNANTS.

Abstract: Purified pentachlorophenol is recovered in good yield by distilling the commercially available grade under reduced pressure in the presence of distillation residues from the Reimer-Tiemann preparation of salicylaldehyde. Preferably water is also added to the material to be distilled. The purified product is nearly colorless and nonblooming and it is essentially free of polychlorinated dibenzo-p-dioxins and phenoxyphenols.
