Preparation of poly (arylene sulfide) |
| abstract |
ABSTRACT OF THE DISCLOSURE: In a process in which a poly (arylene sulfide) is synthesized by reacting a dihaloaromatic compound and an alkali metal sulfide in a polar organic solvent, the curing ability of the product polymer is significantly enhanced by introducing a small proportion of a hydroxyl group-containing polyhaloaromatic compound to the reaction mixture when a conversion of at least 60% has been achieved with respect to the dihaloaromatic compound present in the reac-tion mixture. The product polymer may be advantageously employed in various molding, forming or coating processes to provide the produced articles with increased strengths. The hydroxyl groups introduced into the polymer enable the polymer to be modified, if desired. |
