| 摘 要： | Poly （4- methylphenoxyphosphnzene ） -graft-poly （ ethylene oxide ） （ PPZ-g- PEO ）, a novel amphiphilie grafting polymer was prepared via the Decker-Forster reaction. It is found that the graft efficiency increased with extension of reaction time. Low molecular weight of poly （ ethylene oxide ） favored the grafting reaction. The grafted polymer has two different glass transition temperatures（ Tg） with those of pure poly（ 4-methyl- phenoxy-phopsphazene ） and PEO. The emulsifying ability of grafted polymer was studied with benzene-water mixtare. The emulsifying volumes increased with the decreasing of PEO＇ s molecular weight. The contact angle of film forming from grafted polymer decreased after introduction of PEO grafting chain.

| Abstract: | Poly(4-methylphenoxyphosphazene)-graft-poly(ethylene oxide) (PPZ-g-PEO), a novel amphiphilic grafting polymer was prepared via the Decker-Forster reaction. It is found that the graft efficiency increased with extension of reaction time. Low molecular weight of poly(ethylene oxide) favored the grafting reaction. The grafted polymer has two different glass transition temperatures(T_g) with those of pure poly(4-methylphenoxy-phopsphazene) and PEO. The emulsifying ability of grafted polymer was studied with benzene-water mixture. The emulsifying volumes increased with the decreasing of PEO's molecular weight. The contact angle of film forming from grafted polymer decreased after introduction of PEO grafting chain. |
