ABSTRACT:
A process for the preparation of chlorinated polyvinyl aromatic compound is described, comprising the steps of: (1) in an aromatic organic solvent, forming a solution of an aromatic compound represented by formula (I): ##STR1## wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6 is selected from hydrogen and an alkyl groups containing from 1 to 6 carbon atoms, and R.sup.4 and R.sup.5, or R.sup.5 and R.sup.6 can together form a ring by ##STR2## wherein each of R.sup.7, R.sup.8, R.sup.9, and R.sup.10 is selected from hydrogen and an alkyl group containing from 1 to 6 carbon atoms, and n has an average value of from 50 to 30,000; and (2) subjecting the solution to electrolysis reaction in the pressure of an aqueous solution containing chloride ions.
