摘　　要：设计合成了一种新型的超支化结构的受阻酚,利用IR对其进行了表征。将这种受阻酚作为助剂加入丁腈橡胶和丙烯酸酯橡胶体系中经硫化制备出硫化橡胶,动态力学性能研究发现,这种橡胶具有较好的阻尼性能。而且与小分子受阻酚相比,这种大分子受阻酚在橡胶材料中不迁移,能满足长期储存和使用的需要。A new structure of hyperbranched hindered phenol was designed and synthesized successfully. The designed macromolecule was characterized by IR. This kind of hyperbranched hindered phenol was blended with nitrile rubber and polyacrylate rubber. The latex system was tested by DMA. The result indicated that this kind of hyperbranched hindered phenol could improve the damping property of nitrile rubber and polyacrylate rubber. Compared with former reports, this kind of damping material can met the need of depositing and using for a long time.
