    Abstract: 1,094,254. Polymerizing in a mould. BADISCHE ANILIN- & SODA-FABRIK A.G. March 5, 1965 [March 7, 1964], No. 9403/65. Heading B5A. In a process for making thermoplastic articles by polymerization in a mould, use is made of a jacketed mould 2, Fig. 1, having top and bottom walls 3 and 1 which support a rotatable hollow core 4. The mould walls are preheated to a temperature below the maximum temperature occurring during polymerization and the core is rotated to generate a velocity gradient across the thermoplastic material. To produce profiles the reactants are introduced into the chamber 28, Fig. 5, defined by the rotating core 27 and the wall surface 26. An ultra-sonic vibrator 29 is located at the outlet 25 from which the moulded article is withdrawn by support means 31.

    Abstract: Ethylene may be polymerized by passing into a fluidized bed of granular catalyst consisting of 2% chromium on a silica-alumina carrier, the bed being maintained at 105 DEG C. and 35 atm. to give a product having a molecular weight of 400,000. The reactor comprises distributer plates of special form (see Division B1).
