Process For Manufacturing A Polysulfide Polymer From The Heavy Ends Waste Of Chlorinated Hydrocarbon Production
View pageUS Patent:
54322570, Jul 11, 1995
Filed:
Oct 26, 1994
Appl. No.:
8/329532
Inventors:
Chester Lee - North Plainfield NJ

Assignee:
Formosa Plastics Corporation - Livingston NJ
International Classification:
C08G 7514
US Classification:
528373
Abstract:
A process is disclosed for preparing a polysulfide polymer using a heavy ends waste generated in chlorinated hydrocarbon production. The process involves first pretreating the heavy ends waste by an enriching process to form an enriched heavy ends waste with an ethylene dichloride content less than 10% by weight. The enriched heavy ends waste is then reacted with alkaline polysulfide within a temperature range of 50. degree. C. to 150. degree. C. to form a polysulfide polymer.

International Classification:
C08F28300
US Classification:
525523
Abstract:
A process is disclosed for preparing a polysulfide-epoxy prepolymer and cured co-polymer using a heavy ends waste generated in chlorinated hydrocarbon production. The process comprises first distilling the heavy ends waste to form an enriched heavy ends waste with an ethylene dichloride content less than about 10% by weight. The enriched heavy ends waste is then reacted with an alkaline polysulfide within a temperature range of about 50. degree. C. to about 150. degree. C. to form a polysulfide polymer mixture. Next, between about 5 and about 300 parts of the polysulfide polymer mixture is co-reacted with a hundred parts by weight of an epoxy resin to form a polysulfide-epoxy prepolymer or a cured co-polymer if a curing agent is present.

International Classification:
G06F 17/30

Abstract:
A method and system that organizes and transmits data between systems is provided. The method and system include generating, at a computing system, a graphical user interface including a plurality of user selectable image elements enabling receipt of user data inputs that are used in creating configuration data object. The configuration data object includes structure data that creates a table in database that stores metadata associated with an image file. The structure data defines a format for the table including at least one type of metadata to be stored therein. Monitoring data identifies a location on a data store to be monitored and destination data identifies a location that the at least one type of file is to be transmitted. The system and method also includes monitoring, using the monitoring data of the configuration data object, the identified monitoring location to detect a presence of at least one image file received from an image processing device and detecting, at the monitoring location, a presence of a metadata file associated with the at least one image file and determining if a sufficient amount of metadata is included in the metadata file. In response to detecting a sufficient amount of metadata is included in the metadata file, automatically transmitting the at least one image file and metadata file to the destination location identified in the destination data and creating a table in a database based on the structure data and storing the at least one type of metadata therein.
