| 摘 要： | <正> 聚砜是一类新型热塑性工程塑料,它具有良好的热、电和抗机械性能,但对于化学试剂的抵抗能力较差,易产生环境应力开裂. 尼龙6是一类结晶性的热塑性树脂,具有优异的耐化学试剂能力,它的热扭变温度较低以及对水比较敏感等缺陷导致尼龙材料不能在较高温度下及电器装置的应用中使用.有人曾企图用共混聚砜和尼龙6以改进两者的性能,但实验结果表明无定形的聚

| Abstract: | Polysulfone-Nylon 6 block copolymers were synthesized by the interaction of chloro-terminated polysulfone and liquid caprolactam with sodium metal as condensation agent.Block copolymers were characterized by solubility characteristics, infrared spectro-seopy, dynamic mechanical behavior and differential thermal analysis.The presence of the polysulfone block reduced the water sensitivity of homopoly-mer Nylon 6. |
