The possible mechanism was discussed. These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker. The ATRP of this crosslinker and excess methylacrylate (used as electron-accpetor) was proved to mainly form homopolymers. With the chain-transfer agent S-1-Dodecyl-S\'-(α,α\'-dimethyl-α-acetic acid)trithiocarbonate, the copolymerization of the spiro hydrocarbon, maleic anhydride and MA by RAFT method produced star PMA.

Two sorts of polyacrylate derivates were designed and systhesized. One has benzoic acid groups linked to backbone via an alkyl chain of different length, the other has pyridyl groups at its side chain. On the basis of hydrogen-bonding between carboxyl and pyridyl groups, multilayer film was fabricated in mixed solvents. We studied the effect of either the composition of mixed solvents or length of alkyl chain on the structure of a multilayer film.

Ambient temperature self-crosslinking acrylic latexes were prepared through semicontinuous emulsion polymerization using 3 different polymerizable alkoxysilanes, i.e. vinyl tri silane (A172), Vinyl triethoxy silane and γ-methacryloxypropyl trimethoxy silane (A174). The hydrolysis of these siloxanes under different pH was characterized, and dependence of the latex and polymer properties on these siloxanes and their incorporated amounts in the polymers was studied.
