Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
Process for the polymerization of ethylene at pressures of less than 100 atmospheres and at temperatures up to 100º, approximately with the application of catalysts that are composed of mixtures of metal-organic combinations, especially combinations of aluminum alkyl, with metal combinations of the secondary group 4º.-6º. Of the periodic system, especially with titanic combinations, characterized in that the catalytic components are joined before their application in the reaction vessel and before the introduction of ethylene, being intimately mixed together at room temperature for 1-5 hours, preferably, 40-60º, for a duration of 30 minutes up to 1 hour.
