摘　　要：以自制1,4-二羟基丁烷-2-磺酸钠为亲水单体,聚己二酸己二醇新戊二醇酯(PHNA)、异佛尔酮二异氰酸酯(IPDI)、1,4-丁二醇(BDO)和乙二胺(EDA)为原料,采用丙酮法合成了固含量超过50%的PUD(聚氨酯分散体)。研究结果表明:PUD胶膜的断裂伸长率超过1 500%、最大拉伸强度为47.3 MPa,具有高强度、高弹性之特点;PUD胶膜具有良好的热稳定性(起始分解温度超过280℃,490℃完全分解)和耐水性(吸水率低于10%)。With self-made sodium 1,4-dihydroxybutane-2-sulfonate as a hydrophilic monomer,polyhexanediol neopentyl glycol adipate（PHNA）,isophorone diisocyanate（IPDI）,1,4-butanediol（BDO） and ethylenediamine（EDA） as raw materials,a PUD（polyurethane dispersoid） with solid content above 50% was prepared by acetone method.The research results showed that the PUD film had high strength and high elasticity characteristics because its maximal tensile strength and elongation at break were 47.3 MPa and above 1 500% respectively.The PUD film had good thermal stability（initial pyrolysis above 280 ℃,complete pyrolysis at 490 ℃） and water-resistance（water absorption under 10%）.
