Y. Gnanou et D. Taton, Stars and dendrimer-like architectures by the divergent method using controlled radical polymerization, MACRO SYMP, 174, 2001, pp. 333-341
Using novel multihalide compounds based on 4-tert-butylcalix[4,6,8]arenes a
s initiators, molecularly well-defined polystyrenes (PS) and poly[alkyl-(me
th)acrylates] could be obtained by atom transfer radical polymerization (AT
RP). This core-first approach and therefore the very same initiators also s
erved to derive star block copolymers. Dendrimer-like architectures based o
n poly(ethylene oxide) (PEO) and PS were prepared upon combination of anion
ic polymerization for the inner PEO part and ATRP for the outer PS shell.
