    Abstract: Horizontal tubular reactor, esp. for polymerisation reactions, is provided with a mixer rotating around its central axis, this mixer having the shape of a frame with outer longitudinal plates moving in the immediate vicinity of the internal surface of the reactor wall. Used esp. for the gas phase polymerisation of ethylene, propylene and vinyl chloride.

    Abstract: 1,226,659. Propylene polymerization. BADISCHE ANILIN- & SODA-FABRIK A.G. 9 Aug., 1968 [10 Aug., 1967], No. 38185/68. Heading C3P. Propylene is polymerized in the gaseous phase in the presence of a Ziegler catalyst system wherein purified propylene (which is suitable for achieving a catalyst activity of at least 3000 parts of polymer per part of catalyst per hour; a method of determining the catalyst activity is given in the Specification) is introduced in liquid form into the reaction zone, vaporized and polymerized therein, in the presence of a catalyst whose molar ratio of titanium compound to aluminium compound is in the range of 1: 0À5 to 1: 6. Unpolymerized monomer, on leaving the reaction zone, may be condensed and recycled with fresh monomer. Preferably the reaction is carried out at 10 to 100 atmospheres, 70 to 120‹ C., and using a catalyst comprising TiCl 3 , AlCl 3 and Al(Et) 3 . The homopolymerization of propylene is exemplified and the process is also applicable to the copolymerization of ethylene and propylene.

    Abstract: 1,058,585. Pug-mills. BADISCHE ANILIN- & SODA-FABRIK A. G. Oct. 4, 1963 [Oct. 6, 1962], No. 33298/65. Divided out of 1,058,584. Heading B1C. [Also in Division Fl]. Apparatus for polymerizing ethylene comprises a mixing chamber 1 having at least two inlets 3, a regulatable discharge means 2, and a screw 4 having an axial bore 5 open at the discharge end and communicating with the chamber 1 by means of apertures 6 or the inlet end; in operation part of the materials are recycled through the hollow screw. The apertures 6 may be radial or inclined and may open into the flanks of the screw-thread (see Fig. 2, not shown); they may be circular, oval or slotshaped. The apparatus has heating and cooling means (not depicted), and a thermocouple 9, it may discharge to a degassing screw and a granulating apparatus.
