Abstract

Film-forming, stable, aqueous emulsions of copolymers of ethylene and vinyl chloride are prepared by a process in which ethylene is polymerized in a first step in aqueous emulsion under elevated pressure with vinyl chloride to form a copolymer containing 50 to 75 weight per cent of vinyl chloride and this copolymer is then further polymerized, in a second process step with 5 to 25 weight per cent of vinyl chloride in the absence of ethylene, if desired with the addition of fresh activator, until the product contains 65 to 85 weight per cent of intrapolymerized vinyl chloride. Specified initiators are alkali metal persulphates and perborates and hydrogen peroxide, optionally with reducing agents such as sodium pyrosulphite, sodium bisulphite, sodium formaldehyde sulphoxylate and triethanolamine. Emulsifiers, e.g. fatty acid and modified rosin soaps, alkyl sulphates and sulphonates, alkaryl sulphonates, sodium dioctyl sulphosuccinate, amino alcohol esters of fatty acids, condensates of ethylene oxide with alcohols and alkyl phenols, the ammonium salt of a styrene/maleic acid copolymer and the sodium or potassium salt of a styrene sulphonic acid/maleic acid copolymer. The process may be effected batchwise or continuously, to give emulsions of high solid content suitable for coating glass, paper, leather, textiles and metals. Minor proportions of other monomers, e.g. maleic half esters of aliphatic and cycloaliphatic alcohols or alkali metal and ammonium salts thereof, and salts of polymerizable unsaturated sulphonic acids, may also be present, when conventional emulsifiers may be omitted. In examples, ethylene and vinyl chloride are copolymerized in aqueous media in the presence of potassium persulphate, dipotassium phosphate, and (1) sodium lauryl sulphate, (2) the amide/ammonium salt of a styrene/maleic anhydride copolymer, (3) sodium vinyl sulphonate, (4) monopropyl maleate, and (6) monoethyl maleate.
