Patent number: 5245000Abstract: Poly(arylene sulfide) polymers containing sulfone, ether and biphenyl groups are prepared by a two step process. In the first step, a diphenol is reacted with either a dihaloaromatic sulfone monomer or a bis(haloarylsulfonyl) biphenyl monomer, or both, in the presence of an alkali metal base and a polar organic compound. In the second step, the reaction mixture above is reacted with a sulfur source, and any monomer which was not employed in the first step, if any. The polymers prepared according to the invention process exhibit increased glass transition temperatures over those of known poly(arylene sulfide) polymers. The structure of repeating units of the polymer can be controlled by varying the sequence of addition of the monomers.Type: GrantFiled: July 1, 1991Date of Patent: September 14, 1993Assignee: Phillips Petroleum CompanyInventors: Rex L.
