| 摘 要： | 无规-类接枝共聚物(SFG)由大分子单体-己内酯改性丙烯酸酯(FA)、亲油性单体苯乙烯和甲基丙烯酸缩水甘油酯(GMA)共聚所得，SFG与聚苯乙烯在甲醇溶液中进行自组装，形成核壳结构纳米胶束，进一步对PGMA壳进行化学交联。最终得到具有核壳结构的纳米微球。动态激光光散射和透射电子显微镜表征结果显示SFG自组装形成了窄分布的纳米微球，微球粒径在100～200nm之间。

| Abstract: | Random graft-like copolymer SFG containing polycaprolactone(PCL) oligomer branches, PSt units and a small a-mount of PGMA was prepared. The new approach to preparation of the SFG/PSt nanoparticles through self-assembly of a ho-mopolymer and a random copolymer in methanol solution, form nanometer micelles as core-shell structure. The shell of PGMA can be cross-linked and get core-shell structure nanoparticles finally. Laser light scattering and TEM show the nanoparticles are spherical with narrow size-distribution and the size of the particles is 100 run to 200 run. |
