Abstract: A process for producing sticky polymers at polymerization reaction temperatures in excess of the softening temperature of the sticky polymers in a fluidized bed reactor catalyzed by a transition metal catalyst, which comprises conducting the polymerization reaction above the softening temperatures of the sticky polymers in the presence of about 0.3 to about 80 weight percent, based on the weight of the final product of an inert particulate material having a mean particle size of from about 0.01 to about 10 microns whereby polymer agglomeration of the sticky polymers is maintained at a size suitable for continuously producing the sticky polymers.

Abstract: There is provided a method which reduces fines while maintaining the bulk handling advantages of granular or particulate elastomers such as those produced in gas phase processes and which affords continuous bulk handling of synthetic rubbers or elastomers such as those produced in solution and/or suspension processes. The method comprises (1) feeding an crumb form elastomer or a granular elastomer which contains fines along with optionally one or more filler materials to a mixer/extruder where it is masticated and melted into a compound; (2) pumping the compound through an orifice of the mixer/extruder, and (3) cutting and forming the compound into shaped pellets ranging in size from about 0.5 to 30 mm.

Abstract: A process for the devolatilization of a thermoplastic polymer containing gaseous impurities in an apparatus having a melting zone, a mixing zone, and a reduced pressure zone, comprising: (a) (i) adding a granular blowing agent directly or via a masterbatch to the polymer prior to the introduction of the polymer into the melting zone, said blowing agent being added in an amount of about 1 to about 4 percent by weight based on the weight of the polymer or (ii) adding a gaseous blowing agent to the mixing zone; (b) melting the polymer in the melting zone; (c) mixing the molten polymer and blowing agent in the mixing zone under sufficient pressure to maintain the blowing agent in the mixture; (d) at a temperature sufficient for decomposition or expansion, (i) decomposing the granular blowing agent in the mixing zone and/or in the reduced pressure zone or (ii) expanding the gaseous blowing agent in the reduced pressure zone wherein the blowing agent in its decomposed or expanded state develops froth cells in the molten polymer; (e) in the reduced pressure zone, reducing the pressure at the surface of the molten polymer in a sufficient amount to remove essentially all of the gaseous impurities; (f) optionally, repeating steps (c), (d), and (e) at least once; and (g) recovering the polymer in an essentially unfoamed state. e

Abstract: The present invention provides a process and apparatus for feeding powders such as fine, cohesive, or powdery particulate materials from a low pressure system to a high pressure system. There is provided in a preferred embodiment a process and apparatus of pressurizing and feeding carbon black fluff to a polymerization reactor, particularly a gas phase fluidized polymerization reactor to provide for a close-coupling of a carbon black reactor to a polymerization reactor.

Abstract: Polymers are produced in a stirred bed or gas fluidised bed polymerisation zone of growing polymer particles by (1) introducing a stream of monomer(s), and opt. inert gas(s) or liq(s)., into the polymerisation zone; (2) continuously or intermittently introducing a catalyst; (3) continuously or intermittently withdrawing polymer; and (4) continuously withdrawing unreacted gases, compressing and cooling the gases while maintaining the temp. in the polymerisation zone below the dew pt. of at least one monomer; with the proviso that if there is only one monomer present in the feed stream, an inert gas is also present.
