- Florence KY, US
Hendrich A. Chiong - Cincinnati OH, US

International Classification:

C08G 75/14

Abstract:

A method for forming a polyarylene sulfide with a relatively low content of volatile malodorous compounds is provided. More particularly, such low compound levels may be achieved by selectively controlling the manner in which the polyarylene sulfide is washed after it is formed.

Abstract:

A method for producing a reactive intermediate composition, including: reacting a substituted phthalic anhydride of the formula (I) with a diamine of the formula HN—R—NHin the presence of an aromatic dianhydride in an amount of 10 to 50 mole percent based on the total moles of anhydride functionality in the reaction; wherein the reacting is conducted in an aprotic solvent in a reactor, under conditions effective to produce the reactive intermediate composition; and wherein X comprises a halogen or a nitro group, and R comprises a Caromatic hydrocarbon group or a halogenated derivative thereof, a straight or branched chain Calkylene or a halogenated derivative thereof, or a Ccycloalkylene or a halogenated derivative thereof.

Inventors:

- Florence KY, US
Hendrich A. Chiong - Cincinnati OH, US

International Classification:

C08G 75/14
C08G 75/0281
C08G 75/0204
C08G 75/025

Abstract:

A method for forming a polyarylene sulfide is described. The method can include a multi-step cooling and precipitation process in which the cooling rate of the solution that carries the polymer is decreased during a portion of the overall cooling. This slower cooling period can encompass at least a portion of the period during which the polymer precipitates from the solution. The precipitation process can form polyarylene sulfide particles with good particle integrity and a narrow particle size distribution, which can reduce fines and improve downstream processing and final product characteristics.
