摘　　要：将预分散的纳米氢氧化镁[Mg(OH)2]加入聚氨酯(PU)弹性体反应体系进行原位聚合。结果表明,所得PU弹性体/纳米Mg(OH)2复合材料有较好的力学性能,在聚醚脱水阶段加入纳米Mg(OH)2比扩链阶段加入得到的复合材料力学性能好,纳米Mg(OH)2在PU中基本达到纳米级分散。Nano-meter Mg（OH）2 was dispersed in advance and then added to PU reacting system for in-suit polymerization. The result showed the prepared PU/Mg（OH）2 nano-meter composite had good mechanical properties. The mechanical properties of the composite prepared by adding nano-meter Mg（OH）2 during dehydrolysis of polyether were better than those of the composite prepared by adding nano-meter Mg（OH）2 during chain-extension. The result of TEM analysis indicated that nano-meter Mg（OH）2 particle was dispersed in PU on nano-meter scale ultimately.
