摘要

Mo-2481 PC-071 THE SYNTHESIS OF BIS(4-HYDROXY- DIALKYLPHENYL) SULFIDE A high yield of pure bis(4-hydroxy-dialkylphenyl) sulfide is obtained upon a process comprising the reaction of the corresponding dialkylphenol with a thionyl halide by adding an appropriate solvent to the reaction mixture followed by distillation and recrystallization, said sulfides are suitable as comonomers in preparing polycarbonate resins of improved flame retardance.
