摘要: This invention relates to a method of preparing poly(arylene sulfide) (PAS) from an iodo compound and a sulfur compound, and more particularly, to a method of preparing PAS, including adding a sulfur-containing polymerization terminator when PAS is produced using an iodo compound as an intermediate. Thereby, in final PAS, the residual iodine content may be maintained at the same level or decreased and other properties may be maintained at equal or superior levels, thanks to the use of the sulfur-containing polymerization terminator, which is much lower in price than conventional polymerization terminators.
