Polyarylene sulfide Resin with excellent brightness and method of preparing the same

摘要

A polyarylene sulfide which is prepared from a composition comprising 100 parts by weight of Solid Sulphur, 500 to 10000 parts by weight of iodinated aryl compounds and 0.3 to 30 parts by weight of a Terminator of sulfur-containing polymerization with respect to 100 parts by weight of the solid sulfur, and has a melting temperature (TM) of 255 to 285 degreesAnd a brightness of 40 or more, as defined by the CIE Lab Color Model.In the sulfur-containing polymerization Terminator is at least one selected from the group consisting of 2-mercaptobenzothiazole, n-cyclohexylbenzothiazole-2-sulphenamide,2 - morfolinotiobenzotiazol, N - ndiciclohexilbenzotiazol - 2 - sulfenamida, tetrametiltiuram monosulfuro, tetrametiltiuram disulfide, zinc and ZINC DIMETHYLDITHIOCARBAMATE DIETHYLDITHIOCARBAMATE,And Melting temperature was measured with a differential Scanning calorimeter (DSC).
