A
new dendritic heteroarm star copolymer that contains multi-alternating
arms of poly(ethylene oxide-tetrahydrofuran) (P(EO-THF)) and poly(methyl
methacrylate) (PMMA) on a dendritic polyester core has been synthesized
by a ‘core-first’ approach by combination of sequential cationic
ring-opening polymerization (CROP) and reversible addition–fragmentation
transfer (RAFT) polymerization initiated by a dendritic macroinitiator (3)
capped with multi-alternating terminal carboxylic acid groups (used
directly to initiate the ROP of THF in the presence of EO as a
polymerization promoter to attain P(EO-THF) arms) and dithiobenzoate
groups (used to initiate RAFT polymerization of MMA to attain PMMA
arms). The structures of the products were confirmed by NMR
spectroscopy, GPC-MALLS, and DSC measurements.
