Synthesis of a vinyl monomer containing beta-cyclodextrin and crafting onto cotton fiber

To chemically bond beta -cyclodextrin (beta -CD), which can form inclusion complexes, acrylamidomethyl CD (CD-NMA) obtained from the acid-catalyzed re action of N-methylolacrylamide (NMA) and beta -CD was grafted onto cellulos e fibers using CeIV as the initiator. The double-bond content of CD-NMA inc reased with increase in the NMA/CD mol ratio, and a CD-NMA containing a max imum of three molecules of NMA bonded to a CD molecule could be obtained. S ince the grafting condition is acidic, the hydrolytic stability of CD-NMA i n aqueous nitric acid was studied. The temperature of hydrolysis proved to have a greater effect on the depletion of double bonds from CD-NMA compared with the concentration of the acid. Thus, CD-NMA was grafted onto cellulos e fibers at a low temperature, and FTIR analysis of the CD-NMA-grafted cott on fibers confirmed the chemical bonding of CD-NMA molecules to cellulose.
