Abstract: The present application relates reinforced poly(arylene sulfide) compositions and processes of producing the reinforced poly(arylene sulfide) compositions. The reinforced poly(arylene sulfide compositions can be prepared by blending the reinforcing agent with the poly(arylene sulfide) or by including the reinforcing agent in the process to produce the poly(arylene sulfide). Reinforcing agents which can be utilized are graphenes (e.g., single-walled carbon nanotubes). The inclusion of the graphene reinforcing agent in the poly(arylene sulfide) composition affects the crystallization properties and/or the conductivity of the melt processed poly(arylene sulfide) compositions.
