ABSTRACT:
A method for adjusting the cure rate of a mixture of arylene sulfide polymer particles in which the particles of an arylene sulfide polymer mixture are classified by size groups, the size groups of classified particles are segregated, and at least one size group is removed from the mixture. In a further embodiment at least one size group of classified particles removed from one mixture is added to another mixture of polymer particles. In another embodiment the further use of the segregated size groups of classified particles is based upon a determination of the cure rate of at least one segregated size group of particles.
