Abstract: The preparation of vinyl chloride polymers by polymerisation of vinyl chloride or a mixture of vinyl chloride and one or more other monomers which can be copolymerized with vinyl chloride, with stirring in aqueous suspension, by free-radical polymerisation in the presence of protective colloids, where the polymerisation is terminated after from 70 to 97 % of the polymerisation time to be expected before the pressure drops.

Abstract: 1,2-Dichloroethane is prepared by oxychlorination of ethylene in the presence of a catalyst which contains, on a conventional carrier, copper(II) chloride in a concentration such that the amount of copper ions is from 1 to 20% by weight, based on the total weight of the catalyst, by a process in which the catalyst is obtained by impregnating the carrier with an aqueous solution which contains copper(II) chloride and hydrogen chloride in amounts such that the weight ratio of copper ions to hydrogen chloride is from 13:1 to 130:1.

Abstract: Process for the preparation of 1,2-dichloroethane by reacting ethylene, hydrogen chloride and oxygen in the presence of a supported catalyst, in the form of a solid bed, in only one reaction zone, separating 1,2-dichloroethane and water from the gas mixture leaving the reaction zone, and recycling the waste gas, which contains up to 20% by volume of ethylene, to the reaction zone, fresh ethylene, hydrogen chloride and oxygen being added to the waste gas.

Abstract: 1,2-Dichloroethane is prepared by reacting ethylene, hydrogen chloride and oxygen or an oxygen-containing gas in the presence of a copper-containing catalyst, with hydrogen chloride and oxygen or an oxygen-containing gas initially being reacted in the presence of the catalyst, and then ethylene being added and reacted in the presence of the copper-containing catalyst.
