Improved poly(arylene sulfide) and method of making, and article of manufacture including, the same. |
摘要 |
<p>An improved composite includes an improved polymer, specifically an improved poly(phenylene sulfide). The improved polymer is produced by an improved method including a polymerization phase, a recovery phase, a washing phase, and an optional air-curing phase. In the polymerization phase a low temperature cycle and a high temperature cycle are used. In a preferred recovery phase, solidified polymer is quenched with N-methyl-2-pyrrolidone. In the washing phase, the recovered solidified polymer is washed with a hot acidic solution and then hot water. In a preferred embodiment, the method produces substantially linear poly(phenylene sulfide) having a melt flow within the range of about 50 to about 200 grams per 10 minutes and an ash content of not greater than about 0.1 weight percent and a melt crystallization temperature of not less than about 347 DEG F (175 DEG C).</p> |
