The graft polymerization of acrylonitrile on Crosslinked polyvinyl alcohol microspheres CPVA microspheres was performed by using cerium ammonium sulfate as initiator, and grafted microspheres CPVA-g-PAN were prepared. Subsequently, the grafted PAN was converted into poly via amidoximation reaction with hydroxylamine hydrochloride as reagent, resulting in the functional microspheres CPVA-g-PAO. The chemical structure and physicochemistry characters were adequately characterized with infrared spectrum, scanning electron microscope and determining Zeta potential. The effects of main factors on the amidoximation transform reaction of the grafted PAN were researched with emphasis, and the adsorption property of the functional microspheres CPVA-g-PAO for some biomolecules was examined preliminarily with uric acid as a model biomolecule.

The order-disorder transitions of stoichiometrical AB and A3B alloys werestudied by using effective-atom model based on EAM potential.The results give the analytic function form of the free energy in term of the long rangeorder parameter,and indicate that order-disorder transition behaviors of stoichiometri-cal AB and A3B alloys may be different. This method can be applied to interpret theexperimental results of order-disorder transition in stoichiometrical NiAl and Ni3Al.

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。
