✦ Synopsis

Low molecular weight, low viscosity poly(pheny1ene sulfide) (PPS) has been cured in the melt state to examine effects of curing time and temperature on the melt-state dynamic viscoelastic behavior. It was found that the Newtonian behavior of the uncured material could largely be retained if melt cure temperatures are properly controlled. This result is in contrast to solid-state curing, where the Newtonian nature of the resin is reduced, presumably due to increased branching and cross-Enking as molecular weight builds. The current result indicates that melt-state curing may provide a high molecular weight PPS resin with a predominantly linear molecular architecture.
