Melt Stable Phenylene Sulfide/Sulfone Polymers And Method
US Patent:
5075420, Dec 24, 1991
Filed:
Jan 11, 1991
Appl. No.:
7/640092
Inventors:
Rex L. Bobsein - Bartlesville OK
Robert W. Campbell - Akron OH
Harold D. Yelton - Bartlesville OK
Michael C. Yu - Bartlesville OK

Assignee:
Phillips Petroleum Company - Bartlesville OK
International Classification:
C08G 7514
US Classification:
528388
Abstract:
A phenylene sulfide/sulfone polymer with relatively good melt stability and a method of producing such a polymer are provided. A previously produced phenylene sulfide/sulfone polymer is redissolved in N-methyl-2-pyrrolidone to form a solution. This solution is combined with an alcohol to precipitate highly melt stable phenylene sulfide/sulfone polymer in a particulate form. The alcohol has one to four carbon atoms, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and the like and mixtures thereof.
