Abstract
Methyl 1-trimethylsiloxy-2-[2,5-bis(trimethylsiloxy)phenyl]vinyl ether (6) was used as the initiator for the group transfer polymerization (GTP) of methyl methacrylate (MMA) to give macromonomers with aromatic hydroxyl functions. Quantitative removal of the silyl-protective groups was achieved by acidic or fluoride-catalyzed cleavage to give the deprotected macromonomer 9. The reactivity of this macromonomer in polycondensation reactions was shown by the synthesis of a liquid-crystalline main-chain polyester with poly(methyl methacrylate) (PMMA) side chains (PES-graft-PMMA) (15) and a 4,4′-isopropylidenediphenol-based polycarbonate (PC-graft-PMMA) (19).
