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 (Tg) with those of pure poly (4-methyl-phenoxy-phosphazene) 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.

New coumarin-end-capped polystyrenes have been prepared using functional initiators by atom-transfer radical polymerization (ATRP). In the first case, the photosensitive initiator, 7-chloroacetoxy-4-methyl-coumarin, was prepared. Then the styrene was initiated by 7-chloroacetoxy-4-methyl-coumarin in the presence of a CuBr/bipyridine. The functionalization of the polymers was nearly quantitative, the molecular weight and structure were well controlled by adjusting the monomer/initiator molar ratio, polymerization temperature and time. At high monomer conversion, the polydispersity index of polymer was about 1.40. These coumarin-end-capped polystyrenes underwent [2+2] cycloaddition reaction under UV irradiation in film state. After irradiation the molecular weight and polydispersity index of polystyrene both increased, but the maximum molecular weight was less than the double of original one. It means that the photodimerization reaction was not complete throughly in film state for the diffusion of coumarin groups was blocked by polymeric chain entanglement.

Using Copper nitrate trihydrate (Cu(NO3)2·3H2O) as precursor, hydrazine hydrate (N2H4·H2O) as reducing agent and Ploy(N-vinylpyrrolidone) (PVP) as capping agent in the presence of Diethylene glycol (DEG), highly monodisperse copper particles with different diameters were successfully synthesized via polyol method by different feeding strategies. Dynamic light scattering (DLS) and Scanning Electron Microscope (SEM) were used to characterize the morphology and particle size of these particles. X-ray diffraction (XRD) was used to measure the chemical constituents of these particles. UV-Vis spectrophotometer was used to signify the absorption spectrum of these particles. The results indicated that copper particles with controllable diameter can be synthesized by different injection rates. The average sizes of the prepared copper particles under 2, 4, 6, 8 ml/min of injection rate were 100nm, 200nm, 300nm, 400nm. The obtained copper particles were phase-pure crystalline, and their structure was face-centered cubic (fcc).
