Transparent and little colored polyarylenethioether primary melt molding, preparation and utilization thereof |
摘要 |
A polyarylenethioether primary melt formed article having a Hunter whiteness higher than 30% and a parallel light transmittance Tp higher than 60%, as measured for a sheet with a thickness of 0.3 mm, at the process for obtaining the article which comprises producing a polyarylenethioether according to the polymerization reaction comprising a dehalogenation/sulfidization reaction between an alkali metal sulfide and a dihaloaromatic compound in a polar organic solvent by carrying out the reaction with the addition of an effective amount of a halo-substituted organic compound to obtain a stabilized polyarylenethioether, and then subjecting the polyarylenethioether to melt extrusion. The melt formed article thus produced can be subjected to further melt processing to produce a secondary melt formed article or structure of polyarylenethioether.
