以聚四氢呋喃醚二醇( PTMG)和甲苯二异氰酸酯( TDI)制备预聚体,再用含氢氧化单甲基丙烯酸锌盐( HZMMA)的混合扩链剂扩链制备了不同HZMMA含量的离子聚合物/聚氨酯弹性体( PUE)合金。采用原子力显微镜( AFM)、动态粘弹( DMA)、热重分析( TG)和X射线衍射( XRD)研究了HZMMA含量对离子聚合物/PUE合金的形态结构和性能的影响。结果表明,适量的HZM-MA 能够形成纳米级的poly-HZMMA 粒子,改善了合金中PUE的微相分离程度;poly-HZMMA 能够提高材料的储能模量和软段的最大降解温度;HZMMA发生了自聚且硬段相有结晶。

A series of ionic polymer/polyurethane elastomer alloys were prepared by polytetramethyleneether glycol( PTMG) ,toluene diisocyanate( TDI) and the chain extenders which were consisted of dimethylthiotoluenedia-mine( DMTDA ) , dicumyl peroxide ( DCP ) and hydroxyl zinc mono-methacrylate ( HZMMA ) by the prepolymer process. The effects of different contents of HZMMA for ionic polymer/polyurethane elastomer structure and proper-ties were studied by atomic force microscopy( AFM) ,dynamic mechanical analysis( DMA) ,thermo gravimetric anal-ysis( TGA) and X-ray diffraction( XRD) . The results indicated that nano poly-HZMMA particles were got and the degree of micro phase separation of the PUE were improved when the content of HZMMA was suitable. The nano poly-HZMMA particulars enhanced the storage modulus and improved the maximum decomposition temperature of the soft segment. The HZMMA had the self-polymeric reaction forming poly-HZMMA particles and the hard sege-ments had the microcrystalline structure.
