Synthesis of poly(methyl methacrylate) macromonomers with phenolic functionality by group transfer polymerization and their use in polycondensation reactions
Authors:Thomas Heitz  Owen W. Webster
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 ).
