Cyclodextrins in polymer synthesis: free radical polymerization of cyclodextrin complexes with oxazoline-functionalized vinyl monomers as guest molecules in aqueous medium
Communication: The synthesis of five new oxazoline functionalized vinyl monomers N-[4-(4',5'-dihydrooxazol-2-yl)phenyl]acrylamide (3a). N-[4-(4',5'-dihydrooxazol-2- yl)phenyl]-2-methylacrylamide (3b), N-(10-[-4-(4',5'-dihydrooxazol-2-yl)phenylcarbamoyl]decyl}-2-acrylamide (5a). N-{10-[4-(4',5'-dihydrooxazol-2-yl)phenylcarbamo yl]decyl)-2-methylacrylamide (5b) and N-[4-(4',5'-dihydrooxazol-2-yl)-phenyl]-4-vinylbenzamide (7) is described. With an equimolar amount of 2,6-dimethyl-beta-cyclo-dextrin (DMCD) these monomers formed hydrophilic inclusion complexes 3a,b-DMCD, 5a,b-DMD and 7-DMCD. These complexes were polymerized radically in an aqueous medium. Resulting polymers P-(3a,b). P-(5a,b) and P-(7) precipitated Juring the polymerization due to unthreading of the cyclodextrin from the growing polymer chain. The remaining oxazoline moiety offers possibilities of further modification of the polymers, e.g. grafting in a cationic ring opening polymerization with commercially available alkyloxazolines.
