N-methacryloyl-1-aminopropane (1), N-methacryloyl-1-aminobutane (2),N-methacryloyl-1-aminopentane (3), and N-methacryloyl-1-aminohexane (4) are synthesized and treated with an aqueous solution of randomly methylated beta-cyclodextrin (Me-beta-CD) to form the water-soluble host-guest complexes 1a-4a. In case of the aqueous polymerization of the free monomers 1-4 the initial polymerization rate increases with increasing water solubility. The opposite effect is observed in the case of the polymerizations of the Me-p-CD-complexed methacrylamide monomers 1a-4a. The polymerization rates are increased with increasing alkyl chain length of the complexed monomers 1a-4a and decreasing water solubility of the free monomers 1-4.
