摘要： In a process for preparing aromatic sulfur-containing polymers, the polymer is formed from a prepolymer having halogen end groups. During preparation of the prepolymers, an alkali equivalent and a sulfur equivalent in a ratio of 0.5 to 1:1 is employed in the reaction mixture. The two-step process is particularly suitable for preparing polyphenylene sulfide.
