摘要:
The present invention relates to a method for preparing polyarylene sulfide, in which the polyarylene sulfide is prepared by a polymerization reaction of reactants including a diiodo aromatic compound and a sulfur compound, the method including: further adding 0.01 to 10.0 wt.% of diphenyl disulfide with respect to the weight of the polyarylene sulfide to the reactants to form the polyarylene sulfide having a melting point of 265 to 320 °C.
The diphenyl disulfide included in the reactants according to the present invention costs far less than other conventional polymerization inhibitors to dramatically lower the production cost, and the polyarylene sulfide prepared using the diphenyl disulfide exhibits low iodine content and very excellence in thermal stability.
