Abstract:

The investigation of phenylene sulfide polymers was divided into four areas of endeavor. These are a kinetic study of a model reaction, monomer synthesis, polymerization, and determination of polymer properties. From the results of the kinetic study and monomer synthesis coupled with the early results in the other two fields cuprous p-bromothiophenoxide was chosen as the monomer of choice for the preparation of linear phenylene sulfide polymers. Later work on this monomer showed that a number average degree of polymerization greater than 400 can be obtained either by solid state or solution polymerization. This polymer which has useful polymeric properties is stable in air or nitrogen to 450 C and forms a polymeric residue stable to 900 C under nitrogen.
