微相分离壳层为聚苯乙烯（PS）和聚乙烯（PS）的核壳型微球（乙二醇）（PEG）（微球嵌段：摩尔比：PS/PEG 49.1/45.9 mol %; Mw：PS链：1.07 × 104，PEG链：1.0 × 104; PEG与PS的臂数比：1.0;微球接枝：摩尔比：PS/PEG 33.8/55.9 mol %; Mw：PS链：聚苯乙烯（PS）球型微区的交联，合成了聚苯乙烯（PS）球型微区（PEG链长为1.54 × 104，PEG与PS臂数之比为2.55）（甲基丙烯酸2-羟乙酯）（PHEMA）和聚聚4-乙烯基吡啶（P4 VP）微相分离膜嵌段聚乙二醇甲基丙烯酸羟乙酯嵌段聚苯乙烯三嵌段共聚物（Mn：2.18 × 104;摩尔比：PS 49.1mol%，PHEMA 5.0mol%，PEG 45.9mol%）和聚苯乙烯-嵌段-[聚（4-乙烯基吡啶）接枝聚[乙二醇]嵌段接枝共聚物（Mn：4.56 × 104;摩尔比：PS 33.8 mol %，P4 VP 10.3 mol %，PEG 55.9 mol %; PEG的分支数：2.55）。用透射电子显微镜和小角X射线散射研究了微相分离膜的结构。考察了PS与PEG的臂数比和总臂数对水/苯乳液稳定性的影响。用接枝微球合成的微球提高了水包油的乳化稳定性。© 2003 Wiley Periodicals，Inc.应用聚合物科学杂志91：321-331，2004
Core–shell-type microspheres with microphase-separated shells of polystyrene (PS) and poly(ethylene glycol) (PEG) (microsphereblock: molar ratio: PS/PEG 49.1/45.9 mol %; Mw: PS chain: 1.07 × 104, PEG chain 1.0 × 104; the ratio of arm numbers of PEG to PS: 1.0; microspheregraft: molar ratio: PS/PEG 33.8/55.9 mol %; Mw: PS chain: 1.54 × 104, PEG chain 1.0 × 104, the ratio of arm numbers of PEG to PS: 2.55) were synthesized by crosslinking of spherical domains of poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(4-vinyl pyridine) (P4VP) of the microphase-separated films of poly(ethylene glycol)-block-poly(2-hydroxyethyl methacrylate)-block-polystyrene triblock terpolymer (Mn: 2.18 × 104; molar ratio: PS 49.1 mol %, PHEMA 5.0 mol %, PEG 45.9 mol %) and polystyrene-block-[poly(4-vinyl pyridine)-graft-poly(ethylene glycol)] block–graft copolymer (Mn: 4.56 × 104; molar ratio: PS 33.8 mol %, P4VP 10.3 mol %, PEG 55.9 mol %; branch number of PEG: 2.55), respectively. The structures of microphase-separated films were investigated by transmission electron microscopy and small-angle X-ray scattering. The effects of the arm number ratio of PS to PEG and the total arm number on the stability of the water/benzene emulsion were investigated. The emulsion stability of oil in water was improved by using the microsphere synthesized with the microspheregraft. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 91: 321–331, 2004
