摘要： Solid catalyst components for the preparation of catalysts capable of producing polymers and copolymers of ethylene with ultra high molecular weight are obtained in the form of particles having an average diameter of less than 10 micrometers, by way of reaction, in the presence of H.sub.2 O, between:1) a liquid obtained by reacting:A) a titanium compound containing at least one Ti--OR bond, where R is a C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 cycloalkyl, or C.sub.6 -C.sub.20 aryl radical; withB) a magnesium compound selected from the group consisting of: halides; compounds comprising at least one --OR or--OCOR group bonded to the magnesium, where R is a C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 cycloalkyl, or C.sub.6 -C.sub.20 aryl radical; organometallic compounds; products of the reaction between the above mentioned compounds and electron-donor compounds; and2) a compound or composition capable of halogenating and optionally reducing (A).
