Abstract
Abstract A catalyst and method in which the catalyst is used in association with an aluminum cocatalyst in the polymerization and interpolymerization of 1-olefins. The catalyst is prepared by (1) reacting a mono- or polyfunctional phosphorus compound with silica, alumina or the like having surface hydroxyl groups, or a mixture thereof, in which the phosphorus compound reacts with these surface hydroxyl groups, followed by (2) reacting the product of this with a Group IIa (e.g. Mg) compound and further (3) reacting this product with a Group IVB, VB or VIB (e.g. Ti) compound. Alternatively, (1) is reacted with (3) and then with (2).
