Abstract
1347362 Polymerizing ethylene IMHAUSEN INTERNATIONAL CO 12 May 1972 [15 May 1971] 22297/72 Heading C3P In the continuous polymerization of ethylene in a tubular reactor at at least 300 atmospheres and at most 400‹ C. in the presence of oxygen and/or a radical forming initiator, reactants are introduced at the beginning of the reactor and at at least one point along the reactor, the points of introduction defining polymerization zones, and the quantity and distribution of reactants introduced at the beginning of the reactor and at said at least one point being regulated in dependence upon the composition of the reaction mixture as measured at the beginning of at least one polymerization zone. The ethylene may be copolymerized with a vinyl ester, acrylic compound or alkene, optionally in the presence of up to 25 mole per cent of a moderator. Addition of reactants may also be regulated in dependence on one or more characteristics of the polymer determined as it leaves the reactor, and/or the temperatures measured at a plurality of points along the reactor. Apparatus suitable for carrying out the process is described and illustrated.
