  • Publication number: 20030050414
    Abstract: An enolate functionalized reaction intermediate of general formula (I), wherein X is an alkyl group; Z is selected from the group consisting of alkyl, hydrogen, halogen, alkoxy, thiol, aryloxy or ester; n is an integer and is at least one; Y is alkyl or H; the tetradentate ligand around the Al is optionally substituted. Also claimed is a process for the preparation of the enolate functionalized reaction intermediate and its reaction with a vinylic monomer and a Lewis acid to produce the corresponding vinylic polymer.

  • Patent number: 6469190
    Abstract: An enolate functionalized reaction intermediate, represented by the formula (I) shown in the specification, such as, N,N′-ethylenebis (3,5-di-tertbutylsalicylidene imine) enolate of ter-butyl-isobutyrate aluminum, is useful for the production of vinyl polymers, such as polymethylmethacrylate, from the corresponding vinyl polymers, e.g., methylmethacrylate, by a living polymerization reaction. A Lewis acid may be used in the polymerization.

  • Publication number: 20020022703
    Abstract: 1 A polymerisation process for the preparation of vinylic polymers from the corresponding vinylic monomers which process comprises the step of reacting a vinylic monomer in the presence of a catalyst system comprising a) a metal complex of general formula (I) where A is selected from the group consisting of nickel, iron, cobalt, chromium, manganese, titanium, zirconium, vanadium and the rare earth metals; L1, L2, L3 and L4 are ligands and b) a Lewis acid of general formula (II) wherein at least one of W, Y or Z is capable of formming a co-ordination bond with A and the others of W, Y and Z are bulky groups; D is selected from the group consisting of aluminium, magnesium, zinc and boron.

  • Patent number: 5060945
    Abstract: A game, to be played by two operators, one at each end thereof, simulates a game such as soccer, hockey, ice hockey or the like. A central playing area has a flat surface (11) above which substantially nothing protrudes apart from the players and a simulated ball or the like. The players can be moved towards and away from the operator on members (24) and also can be rotated, as required by means of gears 29 engaged with racks (30, 31) or the like.

  • Patent number: 4772519
    Abstract: Distance piece for mounting an object at a distance from a wall, the piece being formed by a block-shaped body with a flat rear side, and a front side extending substantially parallel to the rear side. The front side is provided with a protruding part and with at least one pair of bore holes extending perpendicularly to the rear side and through the body.

  • Patent number: 4089863
    Abstract: Formaldehyde, acetaldehyde and ammonia are reacted in the vapor phase over a catalyst in the substantial absence of molecular oxygen and in the presence of at least three moles of steam for each mole of total aldehyde reactants. The useful life of the catalyst in the production of pyridine and/or methyl pyridines by this reaction is thereby increased and the coking of the catalyst is reduced.
