An intiator, dimethyl 4, 6-bis ( bromomethyl) isophthalate, was synthesized by bromomethylation, oxidation, esterification and bromination reaction of 1, 3-.dimethylbenzene. The initiator was used to initiate the atom transfer radical polymerization of styrene successfully. The results showed that the process had good characteristics of controlled/living free radical polymerization. The molecular weight of the obtained polymer increases linearly with monomer conversion, molecular weight distribution is very narrow, and a linear relationship between 1n([M](0)/[M]) and polymerization time exists. A well-defined novel structural polystyrene containing two esters groups in the midmain chain was prepared with controlled molecular weight and narrow polydispersity. The structure of the polymer was confirmed by H-1-NMR spectra. After being hydrolyzed, a dicarboxy polystyrene was obtained and used to form ionic-bonded supramolecules with 1-dodecanamine as a model of star-shaped supramolecules. The supramolecules formed was characterized by FrIR spectrum.
