Arylene sulfide polymers. |
摘要 |
<p>Arylene sulfide polymers which can be linear, branched or modified are prepared by a process which comprises the steps of: a) admixing a sulfur source and a cyclic organic amide in the presence of water to form an aqueous admixture wherein the molar ratio of the sulfur source to the cyclic organic amide is at least about 0.6:1 to about 1:1; b) dehydrating said aqueous admixture to form a dehydrated admixture; c) admixing with said dehydrated admixture at least one polymerizable halo-substituted aromatic compound to form a polymerization mixture; d) subjecting the polymerization mixture to polymerization conditions effective to produce the arylene sulfide polymer; and 3) recovering the arylene sulfide polymer.</p> |
