Multistage, Agitated Contactor And Its Use In Continuous Production Of Arylene Sulfide Polymer
US Patent:
43704700, Jan 25, 1983
Filed:
Apr 16, 1981
Appl. No.:
6/254679
Inventors:
Fernando C. Vidaurri - Borger TX Kenneth L. Anderson - Bartlesville OK
Assignee:
Phillips Petroleum Company - Bartlesville OK
International Classification:
C08G 7514
US Classification:
528388
Abstract:
A contacting apparatus that is a vertically elongated, cylindrical shell having closed ends and separated by horizontal baffle plates into a multiplicity of discrete chambers with access from one chamber to another through concentric circular holes, axially centered in the baffles with a continuously rotatable shaft extending concentric with the baffles within the shell with at least one agitator means attached to the shaft positioned in each chamber and with the shaft in the circular openings providing annular openings in the baffles such the the ratio of backflow rate to feed rate through the openings is less than 1. 5. A method for continuously producing arylene sulfide polymer in which reactants suitable for producing poly(arylene sulfide) are introduced into at least a first chamber of the contacting vessel described above thereby forming a reaction mixture which is passed through the chambers of the contactor while maintaining each chamber within conditions for producing arylene sulfide polymer and recovering arylene sulfide polymer from a chamber removed from the chamber into which the initial reactants are introduced.
Arylene Sulfide Polymers
US Patent:
52965791, Mar 22, 1994
Filed:
Feb 11, 1988
Appl. No.:
7/155179
Inventors:
Jon F. Geibel - Bartlesville OK Robert W. Campbell - Bartlesville OK Guy Senatore - Borger TX Fernando C. Vidaurri - Borger TX Mark A. Haney - Algonquin IL
Assignee:
Phillips Petroleum Company - Bartlesville OK
International Classification:
C08F 832
US Classification:
528379
Abstract:
A process for the production of arylene sulfide polymers is provided which comprises subjecting a mixture of at least one first sulfur source, at least one second sulfur source comprised of at least one organic monothiol compound, at least one polyhalo-substituted aromatic compound and at least one polar organic compound to polymerization conditions sufficient to produce the arylene sulfide polymer. The organic monothiol compound can be added at any time prior to substantial completion of polymerization to provide arylene sulfide polymers of increased extrusion rate.
