Synthesis and MALDI-TOF Characterization of β-CD Core ATRP Initiators and RAFT Chain Transfers with Different Degrees of Substitution
-CD derivatives were synthesized as atom transfer radical polymerization (ATRP) initiator or reversible addition-fragmentation chain transfer polymerization (RAFT) chain transfers. The degree of substitution for each derivative was carefully characterized through
1
H-NMR
13
C-NMR spectroscopy and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). The factors influencing the degree of substitution were discussed. Moreover
the comparison between ATRP and RAFT was shown in the polymerization of
N
-isopropyl acrylamide (NIPAM).
