In this work, a series of antimicrobial agents containing the hydantoin structure such as AM, BM and AM-AN, were synthesized by changing the reaction conditions such as temperature, time, concentration of initiator and so on, and the N-halamine structure which possessed the ability of durable antimicrobial, was transformed through a chlorination process.

The experimental results show that hydrophobic association increases obviously with increasing polymer concentration, hydrophobe content, hydrophobic side chain length and temperature. The Critical aggregate concentration of P (AM/NaAA/C8AM) with different hydrophobic content is 1.5~3g/L. Strong association between surfactant sodium dodecyl sulfate and P (AM/NaAA/C8AM) occurs through the formation of mixed micelles. The CMC of SDS is 8×10^(-3)mol/L. Moreover, because of the presence of-COOH group, the terpolymers have pH-responsive characterization. The hydrophobical association changes greatly with increasing pH.

The result indicated that good symbiosis was formed between AM fungi and Avena sativa, and different sample sites significantly affected the colonization of different structure and spore density of AM fungi.

The factors which affect the average molecular weight of the polymer of AM and DMDAAC were investigated. The optimal reaction conditions are as follows: the concentration of monomer AM was 30%, while DMDAAC was 5%; the reaction temperature was 30℃, the amount of initiators at the low temperature stage was 0.05‰(compared to the weight of the monomers joining the polymerization), while V-50 was 0.025‰, the weight ratio of potassium persulphate to sodium bisulphite is 1:1, the amount of carbamide was 40‰, and complexing agent was 0.05‰, besides, aerate nitrogen gas for 8min, then the high molecular weight polymer (M=1.217×10^7) could be got after 16h reaction.

The AMF spore average density was 24.88 per 20 g soil , the species richness was 1.94 per soil sample, the species diversity index was 2.56, and the species evenness was 0.65. Glomus, but they all were of prominent genus in the investigation area and Acaulospora, Scutellospora were of common genus while Entrophospora was rarely found. In the 13 species AM fungi, G.mosseae was of prominent species, and G.geosporum, G.intraradices, G.etunicatum were of common speices, while the others were of rarely species. There were 87.5% sand fixation plant were infected with arbuscular mycorrhizal fungi, the highest spore density, the strongest infection strength of the whole roots and the best species richness belonged to Chenopodiaceae while Polygonacea was the lowest.

Among the open-chain crown ethers and cryptands with a same structure, the compounds disubstituted at the amide nitrogen atoms show the larger extractability for Am and Eu than the monosubstituted ones. The compounds disubstituted at the amide nitrogen atoms by two phenyl groups show the larger extractability for Am and Eu than those by two alkyl groups.
