| 摘 要： | 用微乳液聚合物制备聚－４－乙烯吡啶纳米粒子，用光子相关光谱仪和粘度法分别测定了－４－乙烯吡啶粒子的粒径，粒径分布和分子量。结果表明，聚－４－乙烯吡啶粒子的粒径和分了量随引发剂用量的增加而降低，而单体浓度的增加使聚合物的粒子直径变大。在给定条件下，可以得到粒径小于１００ｎｍ，分子量大于１０＾５的聚－４－乙烯吡啶纳米粒子。

| Abstract: | Vinylpyridine was polymerized in O/W microemulsion made with anionic surfactant sodium dodecyl sulfate (SDS). The effects of monomer concentration, initiator concentration on particle diameter and molecular weight of poly 4 vinylpyridine were investigated, the particle diameter and distribution of poly 4 vinylpyridine were measured with photon correlation spectroscopy and molecular weight was measured with viscometry. The result showed that particle diameter and molecular weight of poly 4 inylpyridine decrease as the initiator concentration increases, the particle diamter increase with increasing monomer concentration. The poly 4 vinylpyridine with diameter<100nm and molecular weight>10 5 was prepared successfully. |
