Abstract

1,196,183. Polymerizing ethylene. STAMICARBON N.V. 5 Feb., 1968 [9 Feb., 1967], No. 5695/68. Heading C3P. Ethylene polymers are prepared by a process which comprises partially polymerizing ethylene feed in a first reactor wherein the reactants circulate internally during polymerization, and passing the effluent therefrom to a tubular second reactor wherein the said effluent passes substantially straight through and unpolymerized feed is polymerized therein at 100‹ to 400‹ C. and over 500 atmospheres. Reaction in the first reactor may be initiated by a coordination or supported oxide catalyst or by high energy radiation. The first reactor may be an autoclave which may have two or more zones in which different reactions prevail. Part of the monomer may be fed cold to the tubular reactor, optionally at a plurality of points, and the reaction therein may be controlled by periodic pressure changes. The ethylene may be copolymerized with acrylic and methacrylic acids, esters and amides, and vinyl acetate. In examples apparatus comprising an autoclave with stirring means and a tubular reactor is used for the polymerization of ethylene in the presence of propane, oxygen and hexane solutions of lauroyl peroxide or t.-butyl perbenzoate.
