Disclosed is a process for polymerizing vinyl chloride monomer in the presence of light. A mixture is formed of liquid vinyl chloride monomer, preferably about 10 to about 250 ppm of a metallocene catalyst, about 1 to about 2000 moles of an aluminum-containing cocatalyst per mole of catalyst, and up to about 500 moles of a Lewis base per mole of aluminum in the cocatalyst. Selected alkyl groups from the aluminum-containing cocatalyst can be placed on the ends of the poly (vinyl chloride) chains.

Disclosed is a method of making trichloromethoxybenzene. A mixture is prepared of anisole and a source of chlorine free radicals, such as chlorine or sulfuryl chloride. The reaction is performed in a solvent, which can be either benzotrifluoride, orthochlorobenzotrifluoride, metachlorobenzotrifluoride, parachlorobenzotrifluoride, or dichlorobenzotrifluoride. The mixture is exposed to actinic radiation, such as ultraviolet light, which generates the chlorine free radicals.

Disclosed is a process for making orthorhombic Na. sub. 2 SO. sub. 4 containing less than 0. 1 ppm chromium from a solution of Na. sub. 2 SO. sub. 4 containing 0. 1 to 100 ppm Cr(III). The Cr(III) is oxidized to Cr(VI) at a pH greater than 7, water is evaporated from the solution to precipitate the orthorhombic Na. sub. 2 SO. sub. 4, and the precipitated orthorhombic Na. sub. 2 SO. sub. 4 is separated from the solution.

A method of removing HMO. sub. 2. sup. - anions from an aqueous silicate solution comprising contacting the solution with a cationic ion exchange resin, where M is manganese, zinc, copper, nickel, or a mixture thereof. The method is particularly applicable to solutions of sodium silicate or potassium silicate.
