【摘要】 用ＤＳＣ、ＷＡＸＤ、ＩＲ等对在０．１ＭＰａ～０．６５ＧＰａ压力下尼龙１１（ＰＡ１１）的结晶样品进行了研究。分析了压力对ＰＡ１１结晶的影响。研究了加入１％液晶聚合物对ＰＡ１１结晶的诱导作用。结果表明：压力有助于ＰＡ１１晶形的完善，液晶聚合物对ＰＡ１１的结晶有明显的诱导作用，使ＰＡ１１在较低的压力（０．１ＧＰａ）和较短的时间（１５ｍｉｎ）内即可得到较为完整的结晶。更多还原

【Abstract】 The crystallization of Nylon-11 under pressure from 0.1MPa to 0.65GPa was investigated by the DSC、WAXD and IR. The effect of pressure and liguid crystal polymer(with 1% LCP) on the crystallization of Nylon-11 was discussed. The result shows that more perfect crystal could be formed under the pressure and liquid polymer could induce the crystallization of Nylon-11. And a perfect crystal could be formed on lower pressure and in shorter time.更多还原
