K. Sakamoto et al., PREPARATION OF HYPERBRANCHED POLYMETHACRYLATES BY SELF-CONDENSING GROUP-TRANSFER POLYMERIZATION, Chemistry Letters, (12), 1997, pp. 1245-1246
Hyperbranched polymethacrylates were synthesized by group transfer sel
f-condensation polymerization of 2-(2-methyl-1-triethylsiloxy-1-propen
yloxy)ethyl methacrylate. The hyperbranched structure of the polymer w
as characterized by C-13 NMR spectroscopy. The extent of the branching
depended on the nucleophilic catalysts used for activation of the mon
omer.
