ABSTRACT:
The addition of cure retarders chosen from among the following classes of compounds: tetraoxaphosphaspiroundecane, 4-hydroxybenzyl isocyanurate, N-hydrocarbylthiophthalimide, and trihydrocarbyl trithiophosphite improves the melt stability and reduces the melt viscosity of arylene sulfide resins, such as poly(phenylene sulfide) resin.
