    摘要: A process for the production of EPM or EPDM comprising contacting ethylene, propylene, and, optionally, one or more dienes, in a fluidized bed, at a temperature at or above the sticking temperature of the product resin, under polymerization conditions, with(i) a prepolymer containing a transition metal catalyst precursor with the proviso that the prepolymer is not sticky at the process temperature;(ii) a hydrocarbyl aluminum and/or a hydrocarbyl aluminum halide cocatalyst,; and, optionally,(iii) a halocarbon promoter; and, optionally,(iv) an inert particulate material having a mean particle size in the range of about 0.01 to about 150 microns wherein the particulate material is either contained in the prepolymer or is independent of the prepolymer,wherein the amount of prepolymer or the combined amount of prepolymer and inert particulate material is sufficient to essentially prevent agglomeration of the fluidized bed and the product resin.

    摘要: A finishing process for a polymer containing an active catalyst residue. Starting polymer has a crystallinity of less than 10 percent by weight and is maintained in an essentially oxygen free reaction zone at a temperature less than polymer sticking temperature. The polymer is stabilized and acids neutralized by adding 2, 6-di-tert-butyl-4-alkyl phenol and/or alkyl -3-(3-5 -di-tert-butyl-4-hydroxy phenyl)- propionate and zinc oxide, hydrotalcite, or a zeolite. Resulting polymer is then treated with catalyst deactivators including water, and then mixed with photo-oxidative stabilizers.

    摘要: A flame spray system employs splatter blocking and automated rod delivery apparatuses. The splatter blocking apparatus includes a barrier member and an actuation mechanism. The barrier member is adapted to be moved between a blocking position in which the barrier member is extended across a spray path from a flame spray gun of a flame spray system preventing travel of particles of fusible material from the flame spray gun to a product being coated and an unblocking position in which the barrier member is displaced from the spray path of the flame spray gun permitting travel of particles fusible material from the flame spray gun to the product being coated. The actuation mechanism is connected to the barrier member and adapted to be selectively actuated to move the barrier member between the blocking and unblocking positions. The automated rod delivery apparatus includes a magazine having a chamber for holding a plurality of the rods of heat fusible material in a stacked relationship with one another and a feed mechanism adjacent to the magazine and adapted to be selectively actuated to successively engage and transfer a lowermost one of the rods from the stack thereof in the chamber of the magazine out through a front opening of the magazine and into a feed passage of the flame spray gun.

    摘要: A control apparatus is coupled to a flame spray gun for controlling the rate of feeding of a rod of heat fusible material through the gun. The control apparatus includes an electric motor adapted to be drivingly coupled to a flame spray gun and being operable in response to application of a D.C. voltage thereto to generate rotary motion to produce and control feeding of a rod of heat fusible material through the flame spray gun, an A.C. to D.C. converter and regulator device for generating and applying the D.C. voltage to the electric motor, a manually adjustable potentiometer connected to the converter and regulator to vary the quantity of D.C. voltage output applied to the electric motor and thereby control the rate of rotary motion produced by the electric motor, a tachometer coupled to the electric motor for sensing the rotary motion produced by the electric motor and, in response thereto, generating a feedback voltage signal representing the rate of rotary motion produced by the electric motor and thereby the rate of feeding of the rod of heat fusible material through the flame spray gun, and a digital display coupled to the tachometer and receiving the feedback signal therefrom, the digital display being adapted to produce a readout of the feed rate in response to the feedback signal.
