Extrusion Isolation Of Blends Of Rubber And Asphalt

View page
US Patent:
50250442, Jun 18, 1991
Filed:
Sep 25, 1990
Appl. No.:
7/586855
Inventors:
Lance A. Christell - Prospect KY
Fred Y. Kafka - Parkersburg WV
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
C08J 320
C08L 9500
US Classification:
523334
Abstract:
Blends of asphalt emulsions or melts and aqueous elastomeric latices are prepared using a screw type extruder adapted to provide sufficient back pressure within the screw flights of the extruder to express the water from the blend through a vent provided in the extruder.

Process For Removing Chloroprene Dimers From Polychloroprene

View page
US Patent:
49434020, Jul 24, 1990
Filed:
Oct 31, 1989
Appl. No.:
7/429577
Inventors:
Fred Y. Kafka - Louisville KY
Archie R. Bice - Landenberg PA
Donald K. Burchett - Louisville KY
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
B29C 4760
B29C 4776
B29C 7102
US Classification:
264141
Abstract:
Removing chloroprene dimers from polychloroprene by feeding to a screw extruder a polychloroprene latex and coagulating the latex in the extruder, feeding the coagulated latex to a dewatering zone and discharging the coagulated polychloroprene through a flow restriction which heats and pressurizes the polychloroprene to an area of reduced pressure to form a porous crumb. Also, the flow restriction applies back pressure sufficient that the water in the polychloroprene is forced out of a vent port. The polychloroprene crumb discharged from the extruder is heated to strip chloroprene dimer therefrom.

Process For Incorporating Organic Fibrous Fillers In Elastomers

View page
US Patent:
52059723, Apr 27, 1993
Filed:
Oct 28, 1991
Appl. No.:
7/784732
Inventors:
Fred Y. Kafka - Louisville KY
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
B29C 4700
B29C 4776
US Classification:
264101
Abstract:
Incorporating fibrous filler into an elastomer by adding to a screw extruder an aqueous slurry of an organic fibrous filler having a length less than about 25 mm and an elastomer latex, e. g. , polychloroprene latex. The latex and slurry are fed to the extruder and the latex is coagulated in the extruder. The coagulated latex containing fibrous filler is fed to a dewatering zone. The flow of coagulated elastomer is restricted so that water present in the coagulated elastomer is separated by means of a vent in the extruder upstream from the restriction and discharging and recovering the fiber-filled elastomer. The compound can be used for the manufacture of power transmission belts.

Process For The Manufacture Of Photosensitive Materials Having A Low Heat History

View page
US Patent:
49700375, Nov 13, 1990
Filed:
Oct 31, 1989
Appl. No.:
7/429578
Inventors:
Fred Y. Kafka - Louisville KY
Paul T. Shea - Freehold NJ
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
B29C 4706
B29C 4760
B29C 4776
US Classification:
264101
Abstract:
This invention relates to a process for preparing a photosensitive composition having a low heat history which includes: (a) forming a substantially homogeneous dispersion by mixing at least one photoinitiator or photoinitiating system, and at least one binder selected from the group consisting of reactive binders and non-reactive binders in the form of a dispersion provided that when said binder is non-reactive then at least one reactive component is added which is capable of reacting with the photoinitiator; (b) coagulating the dispersion to form a coagulum and a liquid; and (c) substantially removing the liquid to form a photosensitive composition.

Precoagulation Process For Incorporating Organic Fibrous Fillers

View page
US Patent:
52059731, Apr 27, 1993
Filed:
Oct 28, 1991
Appl. No.:
7/784100
Inventors:
Fred Y. Kafka - Louisville KY
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
B29C 4700
B29C 4776
US Classification:
264101
Abstract:
Incorporation of fibrous filler into a styrene-butadiene rubber (SBR) by mixing a fibrous filler, SBR latex and a coagulant, feeding the resulting coagulated fiber-filled SBR latex to a dewatering extruder and through a flow restriction that applies back pressure sufficient that water present in the SBR is forced out of a vent upstream from the flow restriction and discharging the fiber-filled SBR from the extruder.
