Abstract
Atom transfer radical polymerization of template monomer synthesized by introduction of methacryloyl groups into secondary hydroxyl groups of β-cyclodextrin [β-CD] was carried out with 1,3-dibromobutane as an initiator. Then, closing of polymerized methacryloyl groups was carried out by reaction of bromine groups at both ends with 1,3-diamino propane [DAP] or 1,4-diamino butane [DAB]. The macrocyclic poly(methacrylic acid) [PMAA] obtained by hydrolysis of products was analyzed by GPC, MALDI-TOF-mass. It was found that template monomer of β-CD was effective for synthesisof macrocyclic oligomers and that DAP was the preferred closing reagent for the methacryloyl groups polymerized in the template monomer.
