    Abstract: A process for the production of sandwich constructions consisting of (a) an inner ply of polyethylene; (b) adhesionpromoting interlayers applied to both sides of the inner ply and (c) outer plies of metal applied to the two interlayers. It is a characteristic feature of the invention that sheeting is prepared continuously from a special polyethylene by means of a screw extruder at a specific temperature of the material, this sheeting is covered on both sides with a film of a special polymer by means of a pair of rollers, the resultant laminate is then covered continuously by means of a pair of rollers at a specific temperature of the material with metal sheeting having a specific temperature and the whole is combined to form a sandwich panel under a specific roller pressure. The process gives sandwich constructions having particularly good chemical and physical properties in a simple way.

    Abstract: A process for the production of plane three-ply materials for plane building components, which materials consist of a relatively thick inner ply of a thermoplastic and relatively thin outer plies of another thermoplastic. The process comprises preparing a board of polyethylene by means of a screw extruder at elevated temperature and covering the board on both sides with a film of a terpolymer at elevated temperature by means of a pair of rollers to form a sandwich assembly. The terpolymer must have a specific chemical composition; it is prepared from (1) a predominant amount of ethylene, (2) a relatively low amount of an ethylenically unsaturated carboxylic acid and (3) a relatively low amount of an ester of an ethylenically unsaturated carboxylic acid.

    Abstract: A process for the manufacture of thermoplastic fibrids by shredding a solution of a polymeric thermoplastic in a field of shearing forces, said shredding being performed by passing a homogeneous solution of the thermoplastic in an organic solvent, which is a solvent for said thermoplastic only at elevated temperature, through a nozzle having one or more orifices in the form of an annular die into a zone having the form of an impulse exchange chamber which has a mean inlet diameter of from 2 to 20 times that of the circular area equal to the total cross-sectional area of the nozzle orifices through which the homogeneous solution is extruded and a length of from 2 to 30 times its hydraulic diameter, in which chamber the homogeneous solution is cooled such that the thermoplastics material precipitates and in which a turbulent field of shear forces exists, this being produced by the introduction of one or more jets of a gaseous or liquid medium, which jets are located centrally to the annular orifice, into said impulse exchange chamber at a velocity of from 5 to 500 m/s.

    Abstract: Particulate olefin polymers are prepared by catalytic polymerization of monoolefins in an auxiliary liquid containing the monomers to be polymerized in dissolved form and the particulate polymer product in suspended form. The reaction mixture is recycled in a loop to which the starting materials are fed and from which the particulate polymer formed is removed. The essential features are (a) that a side stream is branched off from the loop, (b) that the side stream is caused to pass through a separating zone in which particulate olefin polymer is separated by centrifugal acceleration at temperatures and pressures in the same range as present in the loop and (c) that the separated particulate olefin polymer is discharged through flashing means.

    Abstract: Manufacture of particulate polyethylene by polymerizing ethylene in an agitated bed of dry particulate polyethylene by means of a catalyst system comprising (1) a particulate inorganic carrier and (2) a Ziegler catalyst applied to said carrier. The catalyst system is used in the form of an intimate mixture of the catalyst system with a particulate ethylene polymer having a softening point above the polymerization temperature used, the particles in said mixture being coated with an inert organic material which is solid at 30 DEG C but liquid at the polymerization temperature used. This process makes it possible to obtain particulate polyethylene having a desirable particle size distribution.
