    Abstract: Ethene polymerization by Phillips catalysis is carried out using (1) a supported catalyst, which is laden with chromium, phosphorus and aluminum, and (2) a cocatalyst, (1) being obtained by a method in which (1.1) a catalyst intermediate laden with chromium, phosphorus and aluminum is prepared from a silicate carrier, a selected chromium compound, a selected phosphorus compound and a selected aluminum compound, and then (1.2) the catalyst intermediate is heated in an oxygen-containing gas stream. In this process, the component (1) used is one which is obtained by a method in which, in each case in a specific manner, (1.1) in a first stage, (1.1.1) first a suspension is prepared from (1.1.1.1) a finely divided silicate carrier and (1.1.1.2) an inert organic solvent, (1.1.2) then, (1.1.2.1) in an inert organic solvent, (1.1.2.2) an organic chromium compound is combined with (1.1.2.3) an aluminum trialkyl, (1.1.3) then (1.1.3.1) the suspension resulting from (1.1.1) is combined with (1.1.3.2) a phosphoric acid or phosphite and (1.1.3.3) the product obtained from (1.1.2), (1.1.4) finally, the suspension obtained in (1.1.3) is evaporated to dryness, and then (1.2) in a second stage, first (1.2.1) the intermediate obtained from (1.1) is treated with a stream of nitrogen, then (1.2.2) the intermediate obtained from (1.2.1) is heated in an oxygen-containing gas stream, and finally (1.2.3) the intermediate obtained from (1.2.2) is treated with a stream of nitrogen, and both a lithiumalkyl and a boronalkyl are used as (2).

    Abstract: Highly functionalized polyisocyanates are prepared by reaction of a di- or polyisocyanate with compounds having at least three and/or two isocyanate reactive groups whereby at least one of components have functional groups having different reactivity and whereby the reaction ratio is chosen such that on average the addition product contains one isocyanate reactive group; Highly functionalized polyisocyanates (I) are prepared by (A) production of an addition product containing an isocyanate reactive group and at least two isocyanate groups by reaction of (A1) a di- or polyisocyanate with (A2) compounds having at least three isocyanate reactive groups and /or (A3) compounds having two isocyanate reactive groups whereby at least one of components (A1)-(A3) have functional groups having different reactivity to the opposite functional groups of the other components and whereby the reaction ratio is chosen such that on average the addition product (A) contains one isocyanate reactive group. (B) optionally intermolecular addition reaction of the addition product (A) to form a polyaddition product that, on average, contains one isocyanate reactive group and more than two isocyanate groups (C) reaction of the addition product (A) and/or the polyaddition product (B) with a di- or polyisocyanate (C1). An Independent claim is included for the polyaddition product (B)

    Abstract: Gritty ethylene homopolymers or copolymers with minor amts. of 3-12C alpha-olefins are prepd. by polymerising at 30-150 deg.C and 2-150 bar, using a CrO3 catalyst system comprising (a) a CrO3 catalyst obtd. by (1) loading a porous carrier, consisting of or contg. SiO2, with particle size 50-150 microns, pore vol. 1-3 cc/g, and surface 200-600 square m/g, with CrO3 or a cpd. converting to CrO3, in ratio by wt. of carrier:Cr of 100:0.1-10, and (2) heating the prod. at 400-1100 deg.C in a gas stream free from H2O and contg. more than 10 vols.% of O2, for 10-1000 mins., and (b) a co-catalyst, a Li-alkyl or formula LiR, (R = 2-6C alkyl) in atomic ratio of Cr:Li of 1:0.05-100.
