Abstract
PURPOSE: The polymerization of 2,6-disubstituted-4-halophenol is conducted in a heterogeneous system consisting of water and a solvent insoluble in water in the presence of an interphase-transferring catalyst and a hypohalite salt, thus producing title polymer with high straight chain content, high stability and high weathering resistance.
CONSTITUTION: The polymerization of a 2,6-disubstituted-4-halophenol, such as 2,4,6-tribromophenol is conducted in a heterogeneous system consisting of water and a solvent insoluble in water as chloroform in the presence of an alkali, such as sodium hydroxide, using an interphase transferring catalyst, such as a quarternary ammonium, and hypohalous acid, such as hypochlorous acid or its salt at a temperature of 0W40°C to give the objective polymer.
