摘　　要：介绍了合成聚草酰胺(尼龙-n,2)的主要方法、可纺丝树脂的制备方法及其突出的物理化学性质。聚草酰胺有较高的熔点。共聚的尼龙-9,2/8,2克服了普通尼龙-6或尼龙-12耐水解性差的问题。解释了造成这些性能差异的原因,很可能是奇数型的聚草酰胺和部分偶数型的聚草酰胺可形成不同于普通尼龙的新的双向氢键结构造成的。聚草酰胺及共聚物可望发展成为通用聚酰胺。The main methods for synthesis of polyoxamides and conditions suitable for producing polyoxamide fibers were reviewed. Polyoxamides had high melting points. Copolymers of nylon 9,2/8,2 had hetter properties than ordinary nylon--6 or nylon 12 in terms of thermal stability and resistance to hydrolysis. These properties can be interpreted by u nique hydrogen-bonding structures revealed in previous X-ray crystallographic studies on polyoxamide crystals. It was expected that polyoxamides could be developed into general purpose plastics.
