Controlled Comonomer Distribution Along A Reactor For Copolymer Production
US Patent:

Filed:

11/063028

Assignee:
Fina Technology, Inc. - Houston TX
International Classification:
C08F 210/06, C08F 2/34
US Classification:
526348, 526 64, 526 87, 526901
Abstract:
The tendency of copolymer fluff grains of propylene and ethylene to agglomerate is reduced by injecting at least one olefin comonomer, such as ethylene monomer, into more than one point along the length of the reactor, rather than injecting all of the ethylene at one point. This process reduces the tendency of copolymer fluff grains to agglomerate and cause processing problems as compared with injecting the comonomer at only one point. Copolymer made by this process is expected to have lower substantially amorphous polypropylene content and better organoleptics than copolymer made where the ethylene is injected at only one point. In one non-limiting embodiment the copolymerization reactor is a loop-type reactor.
Apparatus For Maintaining Unreacted Monomer Concentration In A Polymerization Reactor
US Patent:
6042790, Mar 28, 2000
Filed:
Oct 24, 1994
Appl. No.:
8/328179
Inventors:
John D. Hottovy - Houston TX
Frederick C. Lawrence - League City TX
Nelson T. Black - Pasadena TX
Frederick C. Lawrence - League City TX
Nelson T. Black - Pasadena TX
Assignee:
Phillips Petroleum Company - Bartlesville OK
International Classification:
C08F 200
US Classification:
422131
Abstract:
In a polymerization process utilizing a high pressure flash to separate polymer from unreacted monomer contained in the effluent stream from the reactor, the concentration of unreacted monomer in the reaction effluent is determined by withdrawing from the reactor an effective analyzing amount of effluent, exposing the amount to a low pressure flash and analyzing the vaporized portion to determine the concentration of monomer.
