A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

Titanium incorporated mesoporous molecular sieves Ti-MCM-41, Ti-HMS, and Ti-MSU were synthesized through S〓I〓, S〓I〓, and N〓I〓 pathways using cetylpyridium bromide, tetredecylamine, and polyoxyethylene (10) stearyl ether as the structure-directing agents, respectively. The framework structure and the titanium coordination environment of these materials were characterized by XRD, N〓 adsorption/desorption, TG, TEM, FT-1R, DR UV-Vis, and ICP-AES. It was confirmed that the titanium was highly dispersed in the silica-based framework positions, and all samples were free of extra framework titanium impurities. The catalytic performance of these titanium containing mesoporous materials was investigated in the oxidation of styrene with aqueous H〓O〓 as the oxidant.
